A friend of mine in high school had 3 of these - all GS’s, all black. One350 auto, one 400 4-spd, and one 455 auto. Our last day senior year (‘82) he gave me a ride home in the 400 4 spd and he opened it up for me. I’ll never forget that. Haven’t seen hime since, so I don’t know if he still has them, but these have been one of my all-time favorites! Gorgeous cars, and that 455 was a monster!

[@ChicagoRob2]

I rebuilt my ‘72 Stage 1 with 11.5:1 pistons and custom 238/247roller. Like big block Chevys, Buicks do well with lots of compression and cam. That car ran like a M’fer. It was a tire-destroyer.

It's been said the Buick GS in 70 was the fastest muscle car ever produced.

[@OhAncientOne]

In the Jan '70 issue of Motor Trend, they tested 2 identical GS 455 stage 1 cars. One 4pd, one Automatic. They even hired a professional driver. The 4spd ran 13.58 @ 104.5 The Auto ran 13.38 @ 105.5. That held the Motor Trend record until 1980 or '81 when a Porsche Turbo Carrera tied the 13.38

MOTOR TREND PLACED THE 1970 BUICK GS STAGE 1 BEHIND A 427 COBRA AND A 427 CORVETTE. THEY WERE QUICKER THAN THE GS STAGE 1. THEY WERE SPORT CARS/ AND 2 SEATERS. ( THAT WAS M/T )

[@rogerpurdy1709]

I bought my 70 Stage1 in Manchester, Ct in 1983/1984 and drove it to my new home in Hamilton Ohio in 1985. White , black vinyl top with a 4 speed. I paid 1800.00 and sold it for 1200.00? to another 20something kid in Beavercreek Ohio. Never saw it again. When in Ct. I drove it to several Mopar shows, I love 67 to 69 V8 Darts and 70 Chargers, and I remember quite a few Mopar guys giving my the thumbs up. Very nice of them. Think about it a lot this days since old car prices are INSANE. Yes, according to MotorTrend it was the fastest 4 seater muscle car running a 13:36 in the quarter mile. Muscle Car Review Magazine did the awesome job of covering the famous 3 race shoot out between Roy Badie, avid Mopar guru, in his 70 Hemi GTX, claiming Buicks ran like they have trees tied to them. Thanks Richard Lassiter , was/is? GSCA Gran Sport Club of America president. He won 2 out of the 3 races against what should've been a superior car on paper. I still have the magazine to this day in 2024. Final note. Roy trailered his GTX to the drag strip and Richard drove his car to the event far from his home and drove it home. No doubt with a big smile on his face.

Incidentally, that's how it was ordered new. When a wheel option wasn't checked off, that's what you got. The car was repossessed very early on and the dealership swapped out the steelies/caps for the flashier chrome rally wheels. I was lucky enough to find these correct 14×6 wheels last year and had the caps sitting on a shelf for the last 20 years.

Imagine the poor neighbors, but it is 1970 & this was normal. Love your GS, Here is why. All black & no vinyl roof. Both P/S & D/S mirrors Tacho Dash Wheel arch moulds Sill panel mould Chrome on Black Colour coded match rims Dog Dish Hubcaps Bucket Seats Just needs a centre console to finish it off, but mate it is a fucking awrsome GS love it. Enjoy the rumble before the Woke & LGBT alphabet people & Greenies deam it offensive. Hope to come to the states one day * meet & greet you & you take me for a fang in the beast of all beast.
