Top 5 Worst Cadillacs of All Time: Cars That Weren't the "Standard of the World"

[@markcain5168]

I was working at Caddie dealerships 1982. The HT4100 just about killed the Cadillac Brand. Not only motor problems but HVAC-Steering racks-Fan Modules-Transmissions. I could go on. You nailed it.

[@mikebrunello243]

I bought a 82 sedan DeVille for 45 bucks had the ht4100 200th trans I never pushed a car so much in my life and never would run right it only had 84000 miles on it cause it stayed broken down

[@TVHouseHistorian]

Some friends of our parents had a 1982 Eldorado Biarritz. Looks-wise, it was *magnificently* beautiful. As beautiful as it was, it was every bit as a magnificent maintenance nightmare, for *all* of the reasons you mentioned. Such a shame, because it was teal with white leather and white vinyl Biarritz top. So beautiful, but such a *beast.*

HT4100 doesn't have a "rack". Not to be so picky, but ..edit: I mean anything with HT4100. Right? Right.

[@markcain5168]

1985 Deville . Rack and pinion . HT4100.

[@eddieschwab864]

Is it true that whenever a ht4100 failed hastily while under warranty that they would go straight to replacing it with a 307, which while not a Cadillac engine is definitely an Oldsmobile engine was probably about as Dependable As It Gets in the 1980s. I know subsequently I've seen plenty of them that have ht4100 plates on the side but have 307s under the hood so I'm assuming that was a warranty replacement guidance. Although I'm curious whether they replaced them with the VIN-Y or VIN-9 307.

I think that what happened to Cadillac is definitely one of the saddest chapters in GM’s history. A lot of it can be explained by saying this is what happens when you put bean counters at the top of a car company versus true gasoline in the veins car guys. I read John DeLorean’s book “On A Clear Day You Can See General Motors” and this started back in the ‘60’s when the early ‘70’s cars were being developed. Unfortunately we all suffered.

I worked at a Cadillac dealership cleaning cars as a young kid. Even in the late 90s there were old guys that were still mad about the early 70s Cadillacs. There was a guy named Ernie that was probably 90 at the time he would bring his Buick in every week and make a point to tell someone that he bought nothing but Cadillac until 1973! Now I drive Buicks. He had a beautiful 84 Park Ave in chocolate brown and his wife had a blue Riviera probably like a 90 or 91. He was a good dude always gave me two dollars for extra soap😂.

I read a story about a guy that had a 70s Cadillac, every time he'd hit the brakes, it would make a terrible CLUNK noise. Several dealerships attempted to diagnose it, no one could. He just lived with it for years. One day the window regulator failed in the passenger side door, the door was taken apart, and inside the door, the tech found a full can of beer, with a note on is that said "so... you finally found it." Naturally its removal "solved" the clunk mystery. Needless to say that was his last Cadillac. Maybe it was Ernie!

And even today, V8-6-4 aka displacement on demand, is still problematic. GM, Honda, and others still are plagued with lifter, and cylinder wear issues.

[@paulwindisch1423]

This is mostly due to extended oil changes and customers not wanting to check or maintain the oil. Ignore the oil life monitor and change the oil regularly at 3,000-5,000 miles with quality synthetic oil and it will likely be fine. Also, check the oil level regularly. The use of low-tension piston rings has proliferated the entire industry, so most engines from all manufacturers consume oil at a rate higher than most people are accustomed to. 1 quart every 2,000 miles is what is generally considered normal by most companies today. If you go 8,000-10,000 miles without checking the oil, your engine may have consumed 4-5 quarts.

[@timw8228]

@@paulwindisch1423 Worse yet was GM issued a service bulletin and didn't do a recall for the 2010/11 yrs to stop oil consumption. The high pressure relief valve in the pan for AFM/DoD would spray oil up on the cylinder walls and oil would get pulled into the PVC system above. Not to mention sticking AFM valves that would damage the engine. I couldn't wait to rip it off of my 2010 V8 Camaro.

[@19chucki74]

IMO, the Catera was a nice sedan, the engine and marketing killed it. Though it was reengineered into the highly successful CTS, with a new platform, powertrains and Cadillac specific styling. THAT generation, and ones after that, became the REAL Caddy that ZIGS.

[@paulwindisch1423]

The. Catera was horrible. They claimed it was the Caddy that Zigs, but still used a conventional steering gear with drag links. It did not have rack and pinion steering. It was also extremely heavy for its size. It was within 60 pounds of the Seville and Eldorado, and only 250 pounds shy of a Deville. The heater control valves would leak coolant. The oil cooler cover would leak coolant. The oil cooler would leak oil (into the cooling system necessitating replacement of all hoses). The idler pullies for the timing belt would come apart leading to pistons contacting valves (there was a recall on these from 1997-1999). The cam covers would leak oil into the spark plug wells causing misfires. The crank sensors regularly failed. The Bosch MAF sensors regularly failed like they did in the mid 1980s. And, the electrical system made no sense. Certain circuits were shared with other unrelated circuits. This is no joke, as I was a Cadillac tech at the time; if your Catera exhibits a condition where the radio only works with the ignition off in Retained Accessory Power, and the power door locks don’t work, it’s caused by an auxiliary electric coolant pump that has developed an internal leak and caused a short, which blows one of the Clamp fuses. Matter of fact, that car had three coolant pumps. The traditional one driven by the belt, one auxiliary electric pump for the heater core, and another auxiliary electric pump for afterboil. This pump would run on hot days AFTER the car was shut off along with the cooling fans for the radiator. I’m glad I don’t have to work on them anymore. Good riddance! The only arguable benefit of the Catera was it lead to the design of the CTS, which was a pretty great vehicle.

[@rb89509]

I was in the engine rebuilding business back in the 80's. We wouldn't touch the 4100 because the camshaft ran right in the block without cam bearings. This would directly effect oil pressure and our shop didn't want the headaches of dealing with them.

[@wilsixone]

Unfortunately, I don't know enough about an engine's internal workings to understand what that means, but from a business standpoint I can see why you wouldn't go for such nonsense. I'm sure you ended up working for nothing at times ie: there's no "warranty" for poor engineering. So, this caught my eye because I know of an outside shop to a local Cadillac dealership that did the overflow work on the replacement diesel engines, whether it was to retrofit a conversion to a gasoline engine or just fix or replace the diesel. Anyhow, I heard the were REALLY busy during that time. I ended up buying an 82 Cutlass 4dr with a 350 diesel. It was I think either 1990 or 1991, so it was older but garaged from new AND it had ultra-low mileage. I believe I paid 900 bucks! It drove it back and forth to work from the North Shore of Long Island to right behind Kennedy Airport for a couple of weeks and then it started running crappily and that was the end of it. So I'm stuck with this thing and have no idea who would buy such a car - not running and a car with a bad reputation to begin with. Then I thought of this guy I knew who worked on them 10 years prior. I called the guy and asked if he was interested and he was! Think I sold it to him for $500. The end. 😉

[@patricklanigan]

My father had an 81 Fleetwood with the V8-6-4 that once the system was deactivated was reliable as could be. It was not powerful for the displacement, but offered up decent acceleration and on the highway respectable fuel economy of 22mpg. The DFI or digital fuel injection system had on board diagnostics, that for the time was quite sophisticated. If I recall correctly, the 6.0 Cadillac was used up until 1986 in the commercial chassis Fleetwood with the Rochester 4 barrel carburetors. For 1982 Cadillac would have been better of to put the Olds 307 or Chevy 305 in rather than that bi metal boat anchor, the HT4100. The 307 was used in the later RWD Fleetwoods that carried the Brougham name from 86 until 88 or 89.

[@donreinke5863]

In the mid 1980s, the son of a local appliance dealer bought one of those 1981 8-6-4 disasters, a Fleetwood .It didnt take long for it to suck a valve down, trashing the engine. I had a 1975 Cadillac that was sitting around wrecked, my ex-girlfriend and I pulled out the 500 and dropped it in the 81. Other than the throttle linkage it was a bolt-in swap as the 368 was simply a smaller displacement version of the 500. It was an absolute screamer, being a half-ton lighter than the Sedan de Ville donor car. We took it out on I-70 east of Denver at night (after making sure the CSP/county sheriff was nowhere to be seen) and put the pedal to the carpet quickly burying the needle on the speedometer as the car continued to accelerate. I have no idea how fast we got it up to (we left the 200-4r overdrive trans in it, electing to not use the THM 400 from the de Ville) but Im sure it was well north of 120 mph. Gave it back to the owner and he whined that the stupid fuel economy display no longer functioned, I told him never mind that stupid stuff...just DRIVE THE CAR. Never heard any more complaints about it. Amazingly, the allegedly weak THM 200-4r and the rear end held up to the massive torque those 500s made, at last until he sold the car some years later. We did a similar swap dropping a Pontiac 455 out of an old Grand Ville into a 1978 G-body Grand Prix. That one was a perfect sleeper, beat a lot of guys who thought they had a quick car.

[@DavidPysnik]

The Olds 307 was actually in Fleetwood Broughams/Broughams through 1990. As much as it was better and way more reliable than the Highly Troublesome 4100, I think the worry was people at the time would find it unacceptable to buy a Cadillac that was powered by a lower-division engine. The Olds 307 is still lacking in power, though. I’m not sure why they didn’t at least put the high-output version of that engine in these full-sized beasts, but perhaps it was the terrible GM decision to avoid the gas guzzler tax. If I had been a buyer back then, I would have easily paid it to get a more powerful engine!

Well excuted. Well stated. I liked how you covered so much and said it so well. I see why Cadillac lost goodwill, customers and market segment. It was the engines. It is sad. Just think if they had the 4.5 and 4.9 in the early 1980's. I think time was not on Cadillac's side with the Cimarron, the 4100 V8 and the other engine. They had some great styling after the period you mentioned, but it was the impact this left on the bnrand. By the late 1980's they had to work on getting back on track. The downsing era did not help at all( 1985-1989). The thing I think that kept Cadillac going was the Brougham and the upsized 1989 Deville and Fleetwood. The 1992 Eldorado and Seville helped into the 1990's. I could have bought Cadillacs, but I bought Oldsmobiles( 98 and Toronado) with the 3800 V6 and still got what I wanted. I recall the Catera. I know two people who owned them and got rid of them for the many reasons you stated. The Holden Commodore was better.

[@Paramount531]

I had a used 85 DeVille, Hook and Tow engine notwithstanding, it was a very pleasant car and a nice size. My HT4100 problems were limited to a failed oil pump, I was driving and shut down in about 2 seconds after seeing the oil pressure light. The replacement pump was the upgraded one used in the 4.5. As time went on, my trust in that car was minimal, so selling it was really my only choice. To this day I miss the very comfortable and quiet interior.

Imagine you are Cadillac planners back then. You watched customers on the west coast start to buy Mercedes in the mid 1960s and instead of talking to those buyers and thinking ahead, you bring the 1971 cars to market. They were successful, but began the beginning of Cadillac's malaise era slide with the the build quality problems. Cadillac finally got an "international" car going with the Seville in 1976 and didn't get a smaller Eldo in the showrooms until 1979. But two oil shocks had made your vehicles uncompetitive again so you look at Mercedes and say "hmmmm, that diesel seems to work ok. Don't we build railroad diesels? How hard could it be?" Well that sucked too. Then they screw up the 6.0L big block with the V8-6-4 tech. Then in desperation the Cimarron is brought to market, two years too early in terms of a design that would not be confused for Chevy. And finally, the piece de resistance, the 1982 HT4100. How bad was this engine? Why on earth would you even offer the Buick 4.1L V6 alongside the HT4100 when they had the same mileage???? The only answer is that someone in Cadillac was hedging their bets in case the HT4100 truly sucked (and it did). So not one, not two but four shitty engines in fives years (can't forget or forgive the Cimarron's first 1.8L I4 engine.

[@dmandman9]

The thing about the v8-6-4 was that it was based on a rock solid engine-essentially a de-bored, de-stroked 472 resulting in a 368 cubic inch engine. The same engine without the variable displacement was used in 1980. And it was rock SOLID.

Can't say any of the post-Northstar cars have caught my eye, and I'd be willing to buy an Eldorado ETC, with the caveat that the engine would be a pain in the tail at any given time. I will never acknowledge the Escalade as a Cadillac.

[@charlesjames1442]

Dad had a ‘84 Seville with the HT-4100. It was glacial but never had other problems. He also had a 1980 Fleetwood with the diesel. THAT was glacial and had problems running; even though he kept it in the garage. The Seville he kept for 12 years. The Fleetwood was gone in about 18 months.

I remember walking home from school in Anaheim CA on Loara with our friend and her Dad on occasion would pull up and a gorgeous "65 red cadillac convertible and give us a ride the next 3 or 4 blocks home...White leather and sparkly red outside,,,And they had a pool in the back yard!!

I bought a beautiful 99 Eldorado 4 years ago with 15,442 miles on it. It now has 29,500 and having electrical problems. I've heard alot of horror stories about engine trouble. Would love to see a video of your take on it! These videos are awesome and I'm quite impressed with your knowledge of so many makes and models!!!😎👍👍

[@paulwindisch1423]

The Northstar engine troubles are a little overblown. I’ll try to be honest about them. You WILL have oil leaks if you don’t already. To fix them the engine will need to be removed and the lower crankcase seals replaced with GM engine sealant. They are prone to blowing head gaskets IF the cooling system is not maintained. As long as it’s maintained it will not likely b e a problem. If it is a problem, have Time Serts installed in the block when the repair is done. When I was a Caddy tech, we used to charge 35 hours to do all of the above simultaneously. I don’t recall those having a litany of specific electrical problems, but issues arose from time to time. What exactly is/are your electrical symptoms?

[@pitman6992]

​@paulwindisch1423 Actually, I had a remote start installed n a new stereo system. Somthing is draining the battery n the power lock n alarm system is acting whacky. My mechanic knows it's not the stereo n thinks it is the remote start system. My mechanic recommended taking it to the shop that installed the stereo, they're friends n he thinks they can figure it out. They do remote start systems also, which is where I should've taken it in the 1st place!! Thank u 4 the info on the motor, I will be getting that done. This car is like brand new inside n out, I absolutely luv it! I got it 4 $8800. Garage kept, even smelled new inside!!!😎👍

[@paulwindisch1423]

@@pitman6992 ah, yes, we would also remove the aftermarket remote starters as they caused a plethora of problems, including parasitic draws. The other thing is, for them to get the remote start to work, they will have needed to bypass the anti-theft in the car. Being an Eldorado, I think you still have the black pellet in the square key? That pellet is a resistor that the module needs to read before it will start. Bypassing that means anyone can start it without the key. There could be a draw from the factory electrical system somewhere, but chances are if it didn’t occur until after the installs of the aftermarket equipment, it is related to said equipment. Please enjoy it, those are beautiful cars!

I had a 1983 Sedan de Ville in the 90s that I bought from a senior who quit driving. My expectations were exceeded. At 55K miles the car was in good condition and drove well. The HT 4100 engine used around a quart of oil every 1500 miles but I never saw smoke under any conditions so the condition was minor. It was reliable for the most part. The low power was the problem. The ride quality was great compared to how most all cars try to be sporty now. It was a couch on wheels. The interior had the cheesy fake wood appliqué everywhere but the crushed velvet seats and vinyl trim were reasonably okay in that it did not feel or look super cheap. If I still had it I would spend the money to have someone just put in a Chevy 5.3 or 6.0 in it and integrate things so it would work as if it had come new like that. Nothing like a large body on frame car to handle the poor road conditions.

That's right! Just yeet that 4100 out and put in a LS with the modern trans. You'd get fuel economy and actual power.

Dad bought an 81 diesel Eldorado. It had so many problems the dealer took it back and sold him an 82 diesel Eldorado with all the available options for a discount. Other than being tragically slow the second one worked fine for years until my sister forgot it was a diesel and filled it with regular gas. Dad had a 350 dropped under the hood and drove it for a couple more years. He never bought another Caddy after owning 4 in a row.

[@JohnnyAloha69]

My bad Cadillac stories almost all occurred in the 80’s. First I bought three Eldo’s from a collector, a 69, a70 and a 71. They were good clean cars with low miles but I was shocked by how cheap the 69-70 dashboards and door panels looked and felt, especially given the very high original price point. Also they rode lousy, noisy rough suspension and despite having 375-400 horses they were not quick by any means. The 71 rode much better but the interior quality was even worse and the extra weight and lower horses made it feel like a 305 not a 500. Next my uncle bought a new 180 Fleetwood with the olds 350 diesel. He never had any troubles with it but it could barely maintain highway cruising speeds on any kind of incline on a turnpike. I do recall borrowing it to go skiing in Vermont and being amazed at mileage in the 30’s. Unheard of at that time. However I also recall being unable to maintain 50 mph on some uphill stretches of I-89. A year later my mom bought an 81 Seville with the 368 6-8-4. It drove quite nice and quiet apart from soft brakes and front drive torque steer. She had it 3 or 4 years and surprisingly never had any issues. Power was pretty good by 1981 standards thanks to the big for that year displacement. My uncle then traded his 80 diesel for an 82 Fleetwood with the 4.1. If at all possible, he hated that gutless engine even more than the diesel and it was gone in a year. After 20 years of Cadillacs he bought a Mercedes and never even considered a caddy again for the rest of his life. I was never into Caddies but I can appreciate the style, presence and quality of mid 60’s Cadillacs.

I remember on the Catera there was a door you could open in the glove box to let the a/c blow in and turn it into a sort of cooler. My retired neighbor bought a new 1981 Coupe de Ville with the 4.1L, four barrel V6. I don't recall her having any problems , and she did a lot of traveling with it.

[@Ascotman]

That 4.1L was a Buick V6.

[@CharlesWiningham]

1971 was when the General Motors Assembly Division took over control of the assembly plants, thus the poor quality control and loss of quality reputations that were built over decades. The Catera would have been a great Buick/Opel, if GM had kept importing Opels. The HT4100 was a rush job, when the V8/6/4 was a critical flop.

[@whattheheck1000]

I'm surprised the 1985 DeVille/Fleetwood and 1986 Seville aren't on there. At least the early 1980s Cadillacs still looked like Cadillacs and drove like them (other than the engines). The 1985 DeVille/Fleetwood and 1986 Seville were obviously tarted-up Buicks. They still had HT4100 engines, too. It wasn't until 1988-1989 with the facelifts and the much improved HT4500 engines that things really started to improve. As a brand I feel like Cadillac reached its low around 1986. December 14, 2023 11:48 pm

[@joelmurphy7980]

The 4100 was a turd regardless of year model. I worked in a Caddy dealer in the mid 80's and part of the make ready for new Cadillacs fresh off the transport was to bring them up to full operating temp, lightly load the engine in gear and listen for main bearing knock. GM had to make main bearings in .001" increments for these engines, and it wasn't unusual to have to put main bearings in brand new engines. The cylinders were free standing in the block, meaning no deck surface, which in turn lead to head gasket issues. The long head bolts threaded in just above the pan rail area. Torqueing the heads back down during gasket replacement could easily pull the threads out of the aluminum block which instantly made the engine non-repairable. GM made sealant tabs to be added to the coolant just for these engines to help keep them from dripping at the head gaskets. Add in distributor and cam gear incompatibility issues that destroyed the cam, detonation issues, unreliable electronic engine controls, the aforementioned oil leaks and intake leaks.... and the fact that the transverse mounted FWD V8 designs were enough to make a preacher cuss from a serviceability standpoint..... the 4100 gets my vote as one of the top three worst designs ever penned by an American manufacturer.

[@L.r.e_motorsport]

The 97 Catera, as an Opel Omega is actually a really good car, the "Elite" range were highly equipped, build quality was pretty decent, the 3.0 and 3.2 had a top speed of 155mph, very popular in the UK as Police cars

[@peterwinstonaldredge6927]

Catera: I have to disagree with you. I leased a 1999 Catera that looked exactly like @19:07 mark in the video. It was a beautiful car. It had a Bose sound system with a 12 disc CD changer in the trunk, a single CD in the head unit with a casette player. So all audio bases covered. The sound system sounded amazing. It rode extremely well, got above average gas mileage, was very quick off the line and sounded great doing so. The sun/moon roof was multi-adjustable. I took it on a week-long road trip with four full-sized adult males and the trunk swallowed all of our luggage with ease. The only issue I ever experienced in 36 months, was in the first month the HVAC system went south. It was fully covered under warranty. After that unfortunate incident, I had absolutely no issues with the car. I am glad I spent 3 years with my Catera. For me, it was a great experience.

[@eggbirdtherooster]

[@DSP1968]

A very wisely chosen list, Adam. Having some (yet varying) experience with all of these, cars equipped with the HT 4100 were the worst of the lot. Too underdeveloped and underpowered for the cars it was installed in. During the 1980s and early 1990s, Cadillac seemed to be doing its best to sell the cars of others. Not until the 1992 Seville/Eldorado did the tide begin to turn.

[@johnandrus3901]

What about later, when they introduced the ohc Northstar V8's? They also had problems, with the heads warping from various gasket sealing issues and other problems. Once these things happened, it was cheaper just to replace the engine. If I remember correctly, the engine had to be dropped from the underside of the engine compartment, which required special equipment and made it a pain to do major work. I had a couple of friends with these cars and once the engines went, it was basically better to get rid of the car. Too bad, they were kind of neat cars.

[@MrSloika]

The engine and trans-axle had to be dropped from the bottom. The problem was poor head bolt design. GM didn't get around to fixing the head bolts FOR TEN YEARS, instead they blamed the grenaded engines on lack of maintenance...yanno, the customer's fault. The head bolts were not the only problem that the Sh!t-Star had. Recently I was driving behind a Cadillac equipped with the 4.6. The car was producing so much black/blue smoke I thought it was a Russian aircraft carrier at first.

I'm honestly stunned that Adam didn't place any North Star engine equipped cars on this list. That particular engine was probably the absolute worst engine Cadillac ever installed into their cars, far worse than the 1.8 liter 1982 Cimarron engine. That's why essentially any Cadillac made from 1994-2002 is literally worthless even with very low mileage and excellent cosmetic condition. If I made this list the Northstar cars would be #1 by far over the other choices. I guess Adam either drives a car with this pathetic engine in it or was responsible for marketing or designing those cars. Otherwise it's very hard to understand why it completely missed this list.

[@barrykochverts4149]

Even the legendary Buick 3800 V6 has an Achilles heel not unlike the Caddy 4100 that can land even nice FWD H-Bodies in the junkyard much too early. If you buy one and don't establish whether the Gen II engine has had an intake manifold upgrade, you are getting a car that has a cast-in coolant port running through the plastic plenum that can fail disastrously and hydro-lock the engine with a flood of coolant in the cylinders. I got lucky with mine and saved it before the damage became fatal. Your experience with a lot of GM cars is valuable to people contemplating purchase of one; Please keep it up, Adam!

[@rickadkins3371]

Also, I think the bloated styling around the headlights of early 80’s GM autos across the board is my least favorite styling trend historically. So my vote goes for worst construction AND styling.

[@palmermccall7309]

I can agree with your list completely, with the caveat that I think the '71-72 sedans were beautifully styled. Here's a few that I have owned that are germane to this list, with model year, engine, year that I owned them, MPG/performance, etc: 1972 Miller Meteor Combination Ambulance/Hearse on Cadillac Commercial Chassis, 472ci, circa 1985. The car had been part of my grandfather's funeral home fleet, and had long been relegated to first call duty. Just a monster on 166 in wheelbase, but fun and comfortable, and as a 15 year-old, it was impressive enough to set me on a path of buying used Cadillacs at around 70k miles and running them to about 150k. I think the MPG was around 12-15. 1977 Sedan DeVille, 425ci, circa 1987. Lemon yellow with plaid cloth seats, and fit in perfectly during a year of college in SW Florida. The car felt heavy, though, and only returned about 16 MPG. 1980 Sedan DeVille, 368ci, white with navy leather, owned circa 1988-90. One of the best cars ever. Compared to the '77, the lighter car was as fast as it should have been, and the car was about perfectly balanced, with a perfectly predictable and useful oversteer. 16-20 MPG. I could drive this car 11 hours from WNC to Detroit (school), and still be fresh enough to go out in the evening. Such a good cruising car. Note: The 368 was the basis of the V8-6-4, of course, but if Cadillac had just stuck with the standard version for another decade even, history would be much different. The car was so well-balanced, and with fuel injection and other improvements they likely would have met CAFE targets anyway, or come close! Aside: Parents' friends in Atlanta had a new '81 Coupe DeVille with the V8-6-4, had zero problems, and after the husband passed, the widow traded it on a nice new '87 LeSabre. 1984 Fleetwood, HT4100 with CA emissions, circa 1991. An absolute slug on acceleration, and I don't demand much. But I never had any failures, and MPG was a bit better at 24 Hwy. Around that time, Dad picked up a used '83 Seville HT4100, that wasn't any faster, but seemed a little better balanced and was considerably better to drive. 1986 Fleetwood Brougham, Olds 307ci, owned circa 1999-2004. Not a bad car at all, and I once pushed it to 29.2 MPG on a 4-hour freeway trip across NC one evening. Valve covers began leaking and all the emissions equipment on top was kind of a nightmare, and I wound up replacing the drivers' side twice, because it was hard to seat the cover without displacing the gasket. Also the passenger's side rear brake drum was so stubborn, I had a lower back strain for several days. This car was the beginning of a recovery compared to the early 80s cars/motors, but it was no match for the 1980 Sedan with the 368, and it was kinda crummy that it didn't have an actual Cadillac motor. I thought the '89-93 lengthened DeVilles and Fleetwoods were beautiful cars, but I never had one. People seemed to wear them out, so used ones weren't compelling, and by the time they would have been in my target zone, I was using a cargo van, then later using midsize trucks and Blazer/Envoy models to tow small travel trailers. I've had nearly zero interest in almost anything Cadillac has produced since the Catera, as that seems to have been the point when they pivoted to thinking that their market/competition was BMW for some reason.

Another memory sparked from this video. As a kid my mom always wanted a Cadillac. My dad took me and my mom up to the dealership to drive a new 1983 4-door DeVille. On the test drive there was a pretty good hill on the way back and my dad punched it at around 25mph. That poor little smog choked V8 screamed in muffled protest. Nothing happened except maybe we got to 30 by the top of the hill. My mom liked the car but dad was totally unimpressed. I think the brands debacles of the '80's contributed to the advent of Cadillac's departure from its traditional brand identity at that time, although the whole thing in retrospect appeared to be unintentional. Putting it all behind them, the path ahead became "Art & Science". I wonder sometimes what would have been had they evolved their traditional brand identity? What would that look like today? Would that be successful?

[@daviddunn1377]

We had a '72 Cadillac and it was in many ways the epitome of what Cadillac was at the time, huge V8 and huge interior.

[@adamtrombino106]

Caddy was really caught flat footed with fuel economy regs in the late 70s, early 80s. Buyers still wanted that ultra luxurious full sized car with power. But GM scrapped all its good Caddy V8s. The 364 was ok with the 4-6-8 system deleted. I've worked on several that were. In fact, that was Caddy's "fix" eventually. The 4.1 is still the butt of many jokes, but at the time, mechanics had a nightmare situation of trying to fix an engine that couldn't be fixed.. I recall even into the mid 90s, customers would come in complaining of leaks of all sorts on relatively low mile cars. Our corporate headquarters actually told us to fix it as best as possible, but told the service manager not to warranty ANYTHING. ( which was done with a big red stamp on the customers' invoice) 1 shop near us was replacing 4100s with the improved 4.5s that came out around 1988 ish. As for the Catera..We would see them come in all the time with blown up engines, or engines mechanically out of time. I recall at 1 point we had 3 of them in the yard waiting on crate engines. Recall they used that duck as a mascot in their advertising? We would call Cateras the lame duck.

There were many different v8 engines options within GM at the time the HT4100 "LT8" was introduced. Oldsmobile 260/307. Chevrolet 267/305/350.

I always wanted to ask whomever was in charge of the Cadillac in 1980's why they went out of their way to make such a horrible engine. Maybe Adam has the answer.

My grandpa did trade a 67 for a 71 fleetwood and loved the car. He had it up till 81, then never bought another cadillac. Personally I never cared for the 73-74 exterior.

The catera really should have been based on the commodore and not the omega. Pretty much the same platform, but the commodore had a V8 and sportier suspension.

Our family had a '64 and '72 Sedan de Ville growing up. Mom and dad had a caddy in the 50s I never saw. The '72 was not that bad, but I was 19 when we got rid of it. The fact the buttons were not leather - lol this isn't something we ever noticed but I can see how it could be criticized as not a luxury appointment. The door straps fortunately lasted until we sold it. Plenty of torque but granted hp not so great. My brother had the 8-6-4 nightmare. A neighbor of mine had an early Cimarron, and it always looked like a toy to me.

Lol I’ve just literally finished watching Derek from Vice Grip Garage do battle with an estate sale Cadillac Coupe de Ville with that EFI V8-6-4 and it caused him nothing but headaches. The Catera was a familiar sight on UK roads as the Vauxhall Omega back in the late 90s and early 2000s and it was generally a well respected and popular car. The 3.0 V6 was indeed known for head gasket failure although the smaller 2.5 V6 which we also got didn’t seem to have the same problems. However most cars here had smaller petrol/gas engines or the BMW 2.5 straight 6 diesel. And I live about 4 miles from Ellesmere Port and toured the plant where that V6 was made! Great video
