The Jaguar Mark X is a Forgotten Big Cat

In Jaguar's glory days of Mk2s, E-Types, and XJs lay their flagship performance luxury saloon - the Mk10 and later 420G - a car that despite its failure set the template for both the style and engineering of Jaguar cars for the next fifty years.

One of Jaguar's silliest mistakes was to build the fabulous Mk10 and NOT use the Daimler 4.5ltr V8 in it, at least for the American LHD models. I got a Corgi Mk10 when they first came out and I loved it. Another great video Ed.

[@gregharvie3896]

Hi from Sydney, Australia. David it was so very close to occurring, the fact that it did not occur was not the Jaguar guys fault, but "bmc bozos". It really was so close to occurring. Mark 10's are my favorite car of all cars made in the past 120 + years. I own one and drive it all the time. Like you, I bought the first Corgi color a weird green then I bought 10 more in every color Corgi ever made. Then 2 Dinky toy ones, 4 Norev ones. 2 larger Spot On ones pale blue & bronze/copper one. Plus, British owned Hong Kong made plastic ones. 2 different ones in 1/24th scale, then 4 colors in big spectacular 1/20th scale, finally a huge 1/12th scale pulling a Ferrari F1 GP car on a trailer also in 4 colors, I bought a blue one & was given a red one as a xmas gift when new in 1962. Mint boxed now in 2023 a 1,000 euro toy set !! WHY : in november 1961, my mum collected her special order brand new black mk10 from the factory in Coventry. While temporary rego of BXE106 was sorted & plates attached to car. Norman Dewis showed a young me around the factory where mk10's were finally completed BY HAND & in the parts of the factory where they were on a very basic production line. Mum bought a second new 420G in late 1971. Move ahead 14 years to mid 1975 and Norman Dewis & R.E( lofty) England came to Sydney to present the two new coupes XJC & XJS to the Australian Jaguar concessionaire, Bryson Motors and also to members of the NSW Jag Drivers Club at Bryson Motors beautiful art deco headquarters at Woolloomooloo, (between Hyde Park & Kings Cross in Sydney) Norman Dewis had remembered my mother so Norman and Lofty sat at our table. You could see this was much to Jack Bryson's disgust, after a while Lofty sat with the Bryson's guys, but Norman Dewis stayed at our table the whole time. Mum bought a second one a new 1971 420G. I got to ask Norman Dewis all the bits of trivia I wanted to know, forced by BMC to rename all the Jaguars, there would have been multiple 420's as a numerised version of engine size was to be applied and the new S-type would be a 420, the Daimler version would be a 420, the new Limousine that was in the works would be 420 and the MK10 would be the 420, the BMC people said that there must be something in part bins you could use, so an aluminium G letter off a Guy truck was used. I found that they in mid 1975 were still building special order MK10's, here in Sydney, the Malaysian Embassy received 2 new odd color special order green ones in January 1975. My dad was a specialist US diplomat for this part of the world based in Sydney in the same building in 37 Pitt St, City. One of their drivers flipped the bonnet so I could see it had the Aust Gov't Federal compliance plate fitted and it had stamped 01 75.so new jan 1975. Dewis confirmed still being made to order in mid 1975. Since then, I have seen several more later '70's-built versions and 2 were dressed as 4.2litre mk10's, NOT 420G's and with government compliance plates fitted too and going by the vin sequencing numbers they are well after ones listed in books. Norman Dewis said some were even "zenith sentinels" bullet proof ones for governments. PUNCH line. ALL the different pieces on a 420G were for the still-born Daimler 4.5 litre v8 version, Norman told me so. The Daimler square pressed grill bars or slats, the chrome brass belt line strips, the front mudguard mounted turn signal repeaters, the new dashboard top rail with black plastic padded pieces, the dash top clock, different leather faced seats, different hub caps, the plain black plastic squishy knee protectors on the dash parcel tray (as mk10 in the same color leather as the seats) all were to be the different and defining pieces for the Daimlerized version, Marquis. Norman Dewis confirmed this, however randomly one day unannounced a fleet of trucks turned up, all completed 4.5 litre v8's, all the tooling, replacement spare parts from inventory were all SEIZED by order from BMC Board of Directors, Norman stated that to that day in 1975 NOBODY knew where they were taken to, were they dumped or smelted down, no one knows. So, from September 1966 when that occurred Jaguar for some months were building new 420G's & new 4.2 Mk10's at the same time and were sold for the same price to the penny. Norman said that the mk10's sold first, that both dealers and clients thought 420G sounded stupid and in Norman's word looked "tizzy" with the sparkling chrome strip. Maybe Daimler buyers were wankers and thought extra bling on an identical and badge engineered / named car made it better, who knows. However Norman said that the 4.5 hemi V8 after the overheating troubles that they inherited from BSA buyout were fixed by fitting the superb GM Harrison radiator division crossflow system like all the 4.2 litre mk10's, then Daimler V8 cars ran cool and did not overheat. Norman said with tweaking & in his words "some yanky carby" 4.5-liter hemi V8's delivered 400bhp in "granny" tune that they'd been sending several out to MIRA test track & they could hammer stress free around banked track at approaching 200 mph effortlessly. Also, Jaguar cars had ordered the best 8A Borg Warner tranny like in the 4.2 mk10's beefed up version with a dual range switch pitch lock up torque converter and stall kit, as the transmission in the Majestic Major v8 cars was apparently purely awful. 8A's are identical to what a US Ford person would call a "full house" C4 Cruiseomatic, they're "badge engineered " gearboxes, fitted to the 430 ci, 7 litre Lincoln Continental & the 390 ci, 6.4 litre "green block side oiler police enforcer" fitted to Ford Galaxies which was then the most powerful engine from any company in the USA and for 1965 won Ford 48 out of 52 Nascar races, then for 1966, 35 out of 52 events one after the next with the big Galaxie and NONE when they switched to the new wide body Mustangs late in 1966. With this new Mustang body every race was lost (identical to Steve McQueen's Mustang in the movie Bullett) due to a weak flexing body with cheap "tear out" rear end suspension, low end Yanky junk. I own a 1967 420G, bought in december 2012 from the estate of the first owner, a special order bronze head ultra high output car with the said same tricked up Borg Warner type 8A automatics that were destined for the Daimler version, I also own a 1965 Super Duty Galaxie with the green engine and that same gear box , and I also own a 1965 Lincoln 4 door sedan also with that said same gearbox, I could swap them from car to car and they will fit & work flawlessly. In 1975 I bought a 1965 4.2 litre mk10 & it had the 8A gearbox and later in 1979 I bought rare long wheelbase 1974 series 1 XJ6 special order car also with a high output bronze head, triple HD8 SU's from Jaguar as it had been specially ordered by Jaguar cars Paris as a RHD car to be shipped to Australia when completed, also fitted with the BW 8A tranny, I owned it 32 years the fact that it had been virtually a handbuilt car showed everywhere, flawless, and in an owner chosen deep claret, painted at the VanDen Plas works in London, I can only imagine this with a V8 Daimler engine in it. Because it was it was extremely powerful with the hand built bronze head XK engine & Mk10 carbies. Fitted out as a 6 cylinder Vanden Plas dressed as a Jaguar with NO vinyl roof, & full Vanden Plas interior I sold it to a friend in 2012 when I bought the fantastic low mileage '67 420G. Finally , that day in mid 1975 I asked Norman Dewis what happened to the mk10 test cars with the 4.5 litre Daimler V8's in them, at that time they were still being used for "hack" work by the factory so maybe hiding out there in some former employees' garage, barn or shed one will turn up one day you can only but hope. I have seen 4 unusual mk10's. a Jaguar v12 powered one, a Buick 454ci, 7.5 litre v8 version with a late series2 xj , or series 3 xj GM thm400 automatic attached as with a specially cast for Jaguar case it fitted easily into the mk10 body, a 4 litre Cummins diesel, this was a manual 3.8 litre mk10 and finally a Daimler 4.5 litre V8 one where decades ago from J & D spares at Blacktown NSW, there had been a pretty nasty rear end accident damaged Daimler Majestic Major which was the donor car, the guy with the Cummins diesel car was a motor engineer tech college teacher & he made some kind of adaptor plate to fit the BW 8A automatic onto the 4.5 V8. All of the above mk10's had open heart surgery as original engines had suffered terminal unrepairable engine failures & their ordinary working-class owners loved them and wanted to see them back on the road again and since they could not afford to buy an really good working XK 4.2 engine, this was a way back on the road again. None are in the club now their then owners would by now be in their 90's, but all 4 were both well and tastefully done. So probably hiding somewhere in this huge country.

[@yorkiegilly4355]

I was in the Jaguar owners club and running a 3.4 Mk2 in 1972 ,which wasn"t a bad car but was not exactly reliable and never really lost some faults with early Jags that were never put "right" like the crappy small Dunlop brakes and the problems with head gaskets - a small problem with the water /heating system usually meant a blown head gasket ,not long after .My mates and family thought I was mad running old Jags in my 20s ,but a couple of family members had them and they were so different than anything else at the time . I eventually bought a 420 G off my brother in laws ,business partner who the Tax man was chasing, for £400 and less than 4 years old , a maroon colour with low mileage ,it seemed a bargain ,but when the bills started coming in and around 12 m.p.g . I wasn"t too sure . The carbs seemed to need synchronizing every other week and water was forever finding it"s way into the twin tanks through the hopeless seals in the filler caps atop the tanks . I had owned a fair few large cars and the Jag. never seemed to be that powerful and never seemed nice to drive - although very smooth & comfy .A Merc. Estate and a Citroen Ds Safari Estate were nicer to drive ,slightly better on fuel and had a bigger road presence . I sold the car to a disabled Lady who lost a leg in a motorcycle crash and bought the car after a long test drive aided with the compo from her accident and she loved the car .Lots of cars later I still love Jags . but now own a Rover P6 2200 which is just the job for old retired blokes who just like old cars ,that are fairly easy to fix and at around 25 - 30 m.p.g. easy to live with ?. Nice video review and happy [classic] motoring .

[@TheDarkPhoenix23]

Good video Ed. A few things to note As an American, I can tell you that a big piece of the story too resides in the "Made in the USA is better" complex. Jaguar was competing with not just the cheaper domestic car market here in the US, but also the domestic mindset of 2 generations. ALL foreign cars were viewed as expensive and problem prone. Expensive to not only purchase, but to maintain. Also (and allegedly) parts were not stocked commonly and had to be imported, which meant your car would be sitting for a considerably longer time than anything domestic. The "Big 3", and to a lesser extent AMC (which ironically would be bought by Renault, but that's for another day) helped to fuel this point of view through rigorous advertising. Need proof? The success of the VW Beetle prompted General Motors to respond by introducing the Chevrolet Corvair, a rear engined car with more interior space and a more powerful 6 cylinder. GM assumed that appealing to the "bigger is better" and "No replacement for displacement" crowd, Corvairs would fly off dealer lots. Ralph Nader's book "Unsafe At Any Speed" put that brakes on that, and the Corvair was deemed a failure, even though they were actually quite good by the end. The Japanese were the ones who truly cracked that mindset, with cheap, fuel efficient cars that outlasted their domestic counterparts by a considerable margin. I remember as a kid in the 80's, Jaguars were hugely popular and were quite the status symbol. As an adult, I now own 2 antique Jaguars (76 XJ12c and XJ40 Vanden Plas) and FYI, I don't need to compensate for anything at all. ;-) Keep up the great work!!

My dad had a mk10 for many years, I remember going to school in it and then learning to drive in it. Such an awesome car, I took my girlfriend at the time for a drive around the Port Hills in Christchurch. I remember dad had to put commercial tyres all round because the weight of the car meant normal car tyres got chopped out very quickly. One time we were out for a drive dad was sitting on 100mph and he buried the boot, the old girl kicked down to first gear, and the rev counter shot around to max revs, about 7grand from memory, held there for a bit then changed up. Dad was a self confessed petrol head and we would go for drives on the Canterbury plains and Port Hills because he loved driving the mk10. He also owned a mk2 and a mk7 Jaguar .

From across the pond, Thank you. I was on the car show circuit for 20 years, only came across one Mark Ten. It arrived from Portugal with LHD, in BRG with Cream upholstery and green piping.

It emerged from the car wash glistening, five seconds before its exhaust system! Narragansett Bay

I worked for a used car dealer who tended to deal in this type of motor. Two things I remember about driving the Mark 10. The suspension felt like riding on a pile of interior sprung mattresses. The steering also felt a bit vague. My favourite Jag to drive. The 420. ( Not the 420G )

[@larryham3502]

[@oldandgrey495]

My Dad bought a metallic/silver/grey with red interior one of these in 1961. The official running cost was £12.00 a week while at the same time, that of the RR Silver Shadow was only £10.00. At the time, we frequently travelled from London to the south coast for weekends away, and we needed another comfortable car. Our Wolseley 6/99 was getting a bit tired. I’ll always remember the first time we went out in it one evening to visit friends in Hampstead. When going back to the car in order to drive home, the nearside, rear quarter-light (13:37) had been skilfully forced open to gain access to the nearside rear door interior handle, the front passenger seat had been laid flat (using the chrome lever to the right of the seat) and a screwdriver had been used to force out the walnut surround that held the radio in place. Whoever did this, knew the exact location of the two securing points holding the walnut in place and didn’t cause much damage to the car. The car radio and its surround had gone. The next day we visited Henlys to buy replacements. We were told there was one radio in stock, but there was an 18-month waiting list for the walnut surround. There had been a run on radio thefts from these new Jaguars and this was the way they were stolen. Another memorable journey was one to Birmingham. The M1 had no speed limit at that time and the Jaguar could go very fast. So could the double-deck buses that went from London to the north, (Companies Standerwick, Ribble and Scout) which had rear engines that could take them to 100mph. Dad overtook one at 120mph but as we reached alongside the front of the bus, the car was sucked in towards the side of it. Fortunately we never collided, but the near 2 tons of car felt like a piece of paper in the wind. There was a problem with the height from the road, or lack of it. I think it was about 6” when loaded. The car wouldn’t like to be driven over any of today’s speed bumps. Dad used to hire this car to the studios who used it in programmes like The Avengers.

[@WindlePoones]

Back in the late 60's I never owned a MK10. However, my best friend did. My group of friends at the time would choose to ride in his car rather than the other cars we owned. It was a delight to be a passenger in and to drive. At the time I owned a two tone, (Blue on blue) Vauxhall PABX Cresta, which was a very American looking car, rear wing tail fins etc. I even had a USA sticker on the back rather than the usual GB sticker, oh and a passable mid west American accent. Occasionally we would swap cars for the week-end. He reckond my PABX was a better bird puller and being equipped with a huge front bench seat, instead of the separate front seats, with a consul in the middle, it was a better entertaining environment, if you know what I mean.

I agree with what you say. Like other contributors, I too remember these Jags well. The appropriately lamented late Ronnie Barker's mum lived in the next village to mine, and I still remember the sight of him driving through our village in a Mk 10 (later, XJs of various types). The then cross-ply tyres scrubbed audibly as he heaved the 2 ton behemoth round the bends. Even our village undertaker - most villages in our neck of the woods had their own back then! - had a derelict Mk 10, with visible canvas showing on the front tyres. Ahh, the days before 1 mm minimum tread. This was also the time just before annual MOTs arrived on the scene, and most people didn't have easy access to a tyre pressure check/pump. Most people hardly knew what tyre pressure was! As long as tyres LOOKED alright, there WERE alright! Cross-plies didn't look 'flatter' on the bottom as they were, to all intents and purposes, rigid. Until the pressure was really low, hence scrubbed shoulders, and even side-walls, really. Cars didn't 'handle' in those days so much as slide in a vaguely controlled way. Sorry dude, rambling, me, about the 60s...

The 1970 Cadillac Eldorado was 18 1/2 feet long was fitted with a 500 cubic inch motor ( 8.2 liters) and 400 hp, It would do 0 to 60 in 7.6 seconds and topped out at 125 mph- big but faster than a MK 10 or even a MK2. Caddy was a foot and half longer too. I've owned a Cadillac Fleetwood ( 21 feet and huge ) but the Lincoln continental and Chrysler Imperial were bigger. Having said all this, I would take that MK 10 anyday over American iron as it is just so beautiful. Wish I could find a nice one here in Canada. I always understood that the XK 3.4 litre was a development from the original SXK 3.5 motor from the SS100 and so it's provenance extends further back than 1948.

As a child, I drove in one. My father was a driver for a company's pool of cars for the CEO's. I found it better than a Rolls Royce Silver Shadow. Sadly "our" two tone silver/black 420 was not the best one. Many problems, and after three years, the bonnet hit the battery poles and the car went up in flames. That was it.

[@alexscott7226]

My dad had one of these when I was a kid… I loved it… he got it a month or so before the fuel crisis in 1973… it was pale blue… sad to see it sold…

[@robertfreeman7906]

I had a 63 3.8 Mk10, nice, big and comfy, but a real rust bucket after only 13 years, the exhaust was non existant and the steering well very vague, but 17 mpg not too bad if you remembered to fill both tanks, I sold it on and bought a Truimph 2.5PI, but I did like the Jag, 32VTN

[@drwho534]

One of Jaguars best looking contemporary classic sedans, beautifully proportioned......not too sure about that two-tone paint job though that breaks up the otherwise clean smooth lines? Great video with lots of interesting insight on this 'almost forgotten' Jaguar. Thanks for posting!

[@pouglwaw5932]

You're right- the two-toned side panels looked great on the swoopy-lined fenders of earlier Jag saloons, but the rather straight-sided MKX needed a solid paint color. Not mentioned was that the MKX had well-rounded side panels with no protective trim which invited door dings and scrapes.

My friend has a 2 tone blue Mk 10 with the V12 in it he fitted it well over 30 years ago 4 speed manual with overdrive bloody great car!!

[@ACD54]

A family friend had a Mark X when I was growing up. I went in it a few times, and it was very quiet and comfortable - but even he said it was vulgar.Which it was.

[@TheMRmadhatt]

What made the suspension on these cars so unique was that it had double wish bone rear suspension using a lower wish bone and the drive shaft as the upper wish bone all mounted in a rubber mounted subframe. Hence lots of hot rod builders used Jag rear ends for the suspension set up

[@ChishanFipz]

I first saw electric windows in a MK10 - I thought it was black magic! Lovely example you have there, apart from the colour scheme

[@Tracertme]

I remember these well I always thought it looked more like a squashed frog, but my family at some point owned every other jag in this period.

[@TwinCam]

I can see that, now you mention it.

[@mikegalvin9801]

My college roommate's grandfather had a then new early 70s one in Denver. Beautiful car and had a more classy air than Caddy, Lincoln and Imperial US competitors. It definitely stood out in a country club parking lot and was a great road car. (He once drove us from Boulder to Lincoln Ne for a football game). Unfortunately it needed more service than US or German luxury competitors of the time and Jag's dealer network was generally speaking just not up to snuff.

[@minimaxi802]

The Daimler hearse and limousine was based on this car, black ones usually used as funeral transport, white ones for weddings, and other colours as a mayor's car.

[@LostsTVandRadio]

When I was a kid in the UK in the 60s the Jag Mark X was a head turner and the name alone simply oozed coolness. Looking at it now I'm amazed how "old-style / gentleman's club" it looks. Still, that front end is definitely a proto-XJ6. The 4.2 litre engine sounded enormous to us but, as you say, a 258 cube was a bit pathetic in American terms in the 1960s.

[@thatcheapguy525]

found a 420G in a breakers yard back in the early 1983. from a distance I thought it was a customised XJ because I hadn't seen one before. getting closer it became apparent just how huge the thing was. the car was complete and undamaged sitting next to the site cabin with a price of £150 in the window (about the price of a long-MOT banger at the time). I had dreams of buying it and bringing it back to life but the owner of the garage I was an apprentice at soon killed that idea. for an 18 year old at the time it would have been the coolest car in town. regarding the interior space, American cars of that era had long bonnet/hoods and even longer boot/trunks, with the bit in the middle being a cramped after-thought. we had a Chevrolet Impala SS in from time to time that was so long we couldn't close the garage doors behind it! the original Mini actually felt more spacious inside. its like these cars were sold to people who were trying to make up for something 😉

[@michaelhalsall5684]

US cars of that era were built to impress onlookers rather than be comfortable or practical.

these jags and their daimler brethren I think nowadays find maximum use as stately wedding transport. i recently saw a couple of them in Australia, all decked up for someone’s wedding. beautiful cars indeed! and Ed I loved that descriptor you used - it is absolutely apt. In Black this car would have been the choice of a cigar smoking velvet jacketed Cad Supreme. OR the automobile of choice, of a tuxedo-ed villain with a shady establishment behind the respectable frontage of a West-End Mansion in London. I would even think of Terry Thomas in a Tux and smoking a cigar.

Re: 'underworld links', Angus Sibbet, he of the infamous, Landa/Stafford 'One Armed Bandit' gangland killing, (elements of which inspired part of the screenplay for the film Get Carter), was found murdered on the rear seat of his very own Mk X, (MUP 11D), one winter morning in 1967. I'm sure that the 420G had a couple of, (very minor), upgrades. In a way, I think it kind of adds to the image of these cars that they are, indeed, a bit 'under the radar', so to speak. Another great vid!

[@OldSonyMan]

My Older brother had a Jigsaw (back in the 70's) which featured a painting of what I now know was a bright yellow Mk10 or possibly a 420G. It was driving through the rain and was a 'Fine Picture'. At the same time I had an 'E type' (roadster with le mans headlights) tri-ang pedal car. I wish I'd kept it but 'as is life' I had a crash into my mum's Ford Anglia which smashed it's wrap around windscreen. Later on my dad repainted it luminous yellow (including the wire wheels). "Oh happy days !"

I like Ed's sense of humour, for instance when he converts metric to imperial and says "if you're watching in black and white". I feel somewhat envious that he has the chance to sit at the wheel of everything from a Mini to a Bentley!

I learned to drive in our Mark 10 at sixteen. I utterly loved that car.

[@grahamariss2111]

They built a Daimler prototype with the big Damiler V8, apparently blew away the XJ engined which caused an issue as Jaguar as that was the sporty brand so they never took a Damiler version forward. The Mk X was a real villain car, real 60s London car, not the lads who Rob the bank, but the lads who run the firm.

My parents had one of these. A young policewoman in an old Mini crashed into the back of them, completely destroying the Mini. There wasn't a scratch on the Jag.

[@usernamesreprise4068]

The Daimler version of the XJ6 was actually called the Daimler Sovereign, the Daimler double six as its name suggests was the V12 version of the Jaguar XJ12. badge engineering at its finest the only difference besides the badges obviously was the Daimlers always sported the classic Daimler fluted grill - and no leaping Jaguar on the bonnet of course which from the front made it very noticable.

[@sarkybugger5009]

This brings back memories. My rich stockbroker uncle had one of these back in the 60s. It put our family's Vauxhall Victor in the shade. The closest I ever got to owning a Jaguar was a Bedford camper van which had Jag seats. They were, needless to say, leather, and very comfy.

[@garynguyen4214]

Absolutely fantastic review mate. A lot of stuff I didn't know and very well researched. So refreshing and relaxing to see a review video on YT (or almost any video on YT) with no silly and unnecessary music added in. Even the title screen is a respectful silence. I'm just so sick of stupid music being added in to videos in every second where there is no narration and even many where there IS speaking. A constant distacting undercurrent of sound or music while the person is speaking! So this video and your others are just great in that respect. Also great are the subtle relaxing breaks between paragraphs of vocals. Where the horrible norm these days is to cut these natural pauses out completely, rendering the video an unnatural and stressful hurried mess to watch with all sound and visuals hard cut to pieces and just horrendous to endure. The script is well written and delivered and I agree completely with your analysis and opinion. I grew up around these and the 420G and even as a keen young teenager, mad on cars, I always felt they were too bulbous and heavy looking; looked good from some angles but essentially "not quite there". I wasn't overly keen on the column auto either - I always felt that a floor shift with proper console should have been fitted. But as you say, they were desgined with the Yanks in mind, and that's the setup they preferred in luxury cruisers. No doubt those large wide seats were designed to accommodate the American's signature large wide aah-rses also! The only small criticism I have is that you only keep mentioning the Cadillac as a comparison competitor - but what about the equally impressive and equally luxurious Ford Lincoln Continentals and the Chysler Imperials? The latter, arguably were some of the most well engineered and amazing luxury cars ever made in the USA. And although you mentioned the small displacement engine, you neglected to mention that compared to the V8 loving Americans - the Jag was only a 6 cylinder. No wonder they didn't sell many in the States. If they had had the venerable V12 in it, I'm sure it would have sold a great many more units over there. Thanks for reading.

Thankyou for your obsessive enthusiasm for motoring. Love to hear your drooling lust for Jaguar.

Another Brilliant video Ed, really enjoyed learning about the history of this gorgeous looking Jag.

[@TwinCam]

Thanks as always mate 🙂

[@dennisnichols2411]

Another excellent video! It's worth mentioning a couple of things. For 1961 Ford's Lincoln introduced a quite shrunken Continental, Smaller than the Cadillacs, possibly a smidge less in size than the Mark X, yet packing the 7L M-E-L V8 packing 315-345 BHP (gross). Additionally it came as a 4-door convertible. It was a sales hit and demonstrated that not all US buyers wanted block long luxury cars (Cadillac even introduced a short deck Series 62 Park Avenue to compete). I think a fairer comparison would be Mk X v Continental. The last thing is, Europe a couple years later caught up (and likely passed) with the Mk X with the vast and tech filled Mercedes-Benz 6.3 V8 Grosser. Granted it was more costly and known as a car for tycoons, dictators, and potentates. but there can be a valid comparison with Mk X and the X derived Daimler limousine. I would like your reactions if you get to drive a Mk X!

I grew up in the era that spawned these great Jags. The Mk 10/420G was one of my favourite cars of all time growing up. Wish they made cars like this today. I'd have one in a trice.

[@RodneyMunch8767]

As your title states, I'd forgotten about the Jaguar Mark X. Thank you, Ed, for a highly informative and entertaining video.

[@OrnumCR]

Had two of these. Great cars. Interestingly, the 420G in the clip is sporting the earlier Mk 10 hubcaps. By the time the 10 morphed into the G, the hubcaps were of the same style as the early XJ cars. My two cars were both 3.8’s…with quite a few detail differences to the car shown. Interesting also that this car is minus the chrome swage trims, but, if my memory serves me correctly, two-tone cars were delivered minus these trims. Brought back some good memories…I even wore Doc Marten shoes and boots back in the very early 1990’s too when I had the cars. Interesting to watch this.

[@gregharvie3896]

Hi from Sydney, Australia. Re the hub caps , I bet I know why. In March 1975 I bought a left-hand drive '65 Mk10 4.2 litre. as a 19 yr old I could only afford it as it was a "lepper" with 15months to go before in Aust' 1st July 1976 ALL LHD cars would have their registration cancelled by national law and never be allowed to drive on the road again until; they were RHD, I found a late '68 that elderly Brits' had brought out to Australia from the UK, however they had lived in Tasmania first & then relocated to Sydney where it failed its roadworthy to obtain NSW rego'. I bought it for next to nothing, in May uni break myself & my retired engineer grand-dad did the RHD swap as all the holes and firewall blanking plates are there, just a giant "meccano set " of a swap. NOW, the caps the "genuine" 3.8 & 4.2 mk10 caps , unlike the other Jags of the period are made of thick brass and are very heavy. I put the more modern 420G caps on my '65 mk10 to "freshen" it up and sold it with them on. However, at time of sale the 420G caps had rust spec's on them. In December 2012, I bought a 1967 420G it was a one owner car that had led a careful pampered life. But the only scrappy thing on the whole car was the pitting/rust spots on the hubcaps. I still had wrapped in a thick plastic wool sample bag all the '65 MK10 caps , it had started life in Geneva, Switzerland owned by the Aussie chief of mission to the World Health Organization, where roads are salted in winter, decades on the thick heavy brass mk10 caps are like new. I have fitted those to my 420G as well, I bet you this owner has done the same thing. As the premium car mk10's got brass hub caps when new and other Jags got steel ones that rust.

[@OrnumCR]

@@gregharvie3896 …interesting story Greg, I’m also in Australia and bought my first Mk 10 at 19 y.o. That car was a 1964 3.8 litre-Old English White with red interior trim. I still remember the engine number…ZB2011-8…and the registration plate was (WA) USA-794. It had the heavier hubcaps on, and, as these were on a 14” road wheel, they had interesting chrome rim embellishers that had a screw clip that locked the embellishers onto the rim. It had the Kelsey-Hayes square rubberised brake bellows and the power steering driven off the rear of the generator. I loved the triple S.U. 2 inch carburettors and the commonality of that engine to the Series 1 E-Type. I had some real adventures in that car, and I will say the 3.8 solid deck block was more robust than any 4.2 litre…a far better motor in my opinion. My car didn’t have the old DG auto box, that was swapped for a later model 12. Enjoy your 420G…they’re wonderful cars!!

[@gregharvie3896]

@@OrnumCR H i do drive my mk10/420G all the time both mine have been Cream with Ox-blood a very dark maroon leather trim. All mine have had high output bronze heads I would not touch any Jag aluminium one as you know that you'll get head gasket fails as the two metals cool and warm at different temperatures. My mum had a brand new black November 1961 mk10, they had the power boost set up used by Chrysler for their premium "letter series" cars which had Imperial front end clips with a Chrysler Coupe centre & Imperial rear guards boot lid, light units. These beasts had a strange Mopar "disc" brake system that was half of a real disc brake kind of mixed with a drum brake in a weird cage unit and the identical Kelsey Hayes rubber bladder covered booster, Chev Corvettes with fuel injection in late '50's & early '60's also used the rubber bladder booster and also their own weird "disc" brakes that were similar to Mopar ones in a cage. The 3.8 mk10's have special wheels made to work with the strange Kelsey Hayes system and they flexed hence the screw clips. Jaguar were unhappy with client complaints with early bladder skin fails and with the wheels so went to Dunlop with all the disc brake work Jaguar themselves had done to convert this new WW2 aeroplane braking system to fit a big heavy car. 4.2 wheels and 3.8 car wheels will not interchange unless you pull off the alien brake systems as the wheels foul on the calipers, so jointly Dunlop-Jaguar designed the wheels, brakes & the Sports SP41 Aquajet tyres all to suit the late 1964 introduction of the 4.2 MK10 plus the wheels have the deepest safety ditch for the tyre bead to drop into. Recently I was swapping wheel rims and putting the nicest almost new looking wheel back in as the spare & swapping the tryes. I told the young guy in the tyre place to not use the thin steel shaft to try and break the bead, you will need the big lever arm unit with 2 "legs" attached both with the curved "feet" attached to force stretch the tyre in 2 places over the safety bead drop down. Didn't listen to me as moments later I heard the noise as thin steel tool snapped and the big broken piece became airborne and tore a huge hole in the color bond shed, the almost 18" long missing bit hit something outside as we heard it, but could not see what it hit, he had the wobbles from shock.

[@captaccordion]

Your mention of Daimler reminded me that Jag of course acquired with Daimler the 2.5 and 4.5 V8s. The story goes that a MkX was trial fitted with the 4.5 V8 which blew the doors off the XK 3.8. Nevertheless they killed off the Daimler V8s. One wonders whether the V8 might have been a better idea for US sales, and indeed, whether it may have made the future V12 unnecessary?

[@davidpeters6536]

I just wrote the same message to Ed then scrolled down to read yours. It would have been a shame if the V8 had stopped Jag from making the V12, remember all the Le Mans winners it powered, but it should have gone in the 420G if not the Mk10.

Warm up lap behind the control car and they were off, 30 odd screaming Granada Mk 2's pushing the Jag at a frightening speed ! First corner there was no way it was going to get around the corner and went straight on and taking a thick iron post clean out of the concrete, ripping the wheel right off the Jag, He managed to repair it and got out for the next race.
