Loaded With Options! 1970 Buick GS455 Stage 1

Before the Internet, if a Stage 1 Buick turned up anywhere, in any condition, even if it was red with a blue interior, a local Buick enthusiast (or several) would empty their IRA or their kids’ college fund to buy it. Today that-there World-Wide-Web thingy gives your local sale a national, if not global, audience. Even in that melee this 1970 Buick GS455 Stage 1 outside Vacaville, California stands out. Start with the numbers-matching powertrain, air conditioning, and other power options on top of the wicked Stage 1 performance package, and, with 1970 being the peak year for these cars, it’s no surprise the ad here on Craigslist asks $32,000. Get two Type-A bidders at an auction and this green machine could go for twice that. Did I mention the seller says this classic “runs amazing?” Thanks to reader Matt R. for spotting this well-appointed street monster.

The setting sun makes for a less-than-ideal photo shoot, but what’s presumed to be original Sherwood Green paint (really?) holds a nice shine, the grille is straight, and the bumper looks a bit worn but un-crumpled.

Other than the el-cheapo vinyl wrap on the steering wheel, this Buick looks ready to ride! You might ask for bucket seats with a console-shifted four-speed instead of the bench with column-shifted automatic, but I’d take this look in a minute. Power seat, power windows, power brakes, and power steering combine with air conditioning to make this one fancy muscle car.

Only “GS” badges, sport wheels, and the subtle air holes in the hood suggest this Buick is more than an everyday grocery-getter.

Last but certainly not least we must sing the praises of the mighty Buick 455. Functional air scoops supply the 7.5L monster with cubic hectares of fresh air, appropriately screened to avoid ingesting wayward song birds. I didn’t even know you could get AC on a Stage 1 car! Whoever ordered this beast believed in The Power of “And.” Buick’s sales literature described the Stage 1’s carburetor as having throats “like Carlsbad Caverns.” The carburetor mixes plenty of fuel with all that air while the high-lift cam and other goodies convert the exploded mixture into 360 HP and a stump-pulling 510 lb-ft of torque, according to lov2xlr8. While the $115 Stage 1 option added 10 HP on paper, Hemmings reports it may have generated nearer to 395 HP. HotRod made 426 HP on a 455 setup close to Stage 1 specs. If I buy one of these, I’ll drive it like I own a refinery. Is this Buick’s ultimate muscle car?

    I wish it wasn’t green, but it is still an awesome luxury muscle car. This car is the definition of a luxury muscle car. These pretzels are making me thirsty!

    Fair price if it checks out in person. It’s not cheap, nor should it be, but it’s presentable as it sits and can be worked on and driven at the same time.

    It has a great set of options, largely in tune with current expectations. There are a couple of odd omissions from that list, it has power drum brakes and wasn’t ordered with a rear sway bar.

    GS 455 Stage 1. One of the best Muscle car combos of all time imo. And with 70 being the best looking year Lark, once combined with A/C and the fact that its green, checks all the right boxes for me. Nothing like torque wrapped in class.

    Serious machine from arguably the strongest class of 1970. Just knowing how strong these pull allows me to ignore such an ugly steering wheel. It really is, looks like a late model air bag unit.
    The beast!

      My 70 Lark has the same wheel, and although its black and in mint shape, I agree the design is airbag ugly.

    The only way this car could be any better is if it had the buckets/console/ and rear bumper with exhaust cutouts! Green is o.k. by me! GLWTS!! :-)

    Worst possible color.
    Worst possible transmission.
    Worst possible shifter location.
    Worst possible seats.
    I still want it.

    These cars were nothing but fast and the standard gear on a Stage 1 with air was 3:42 one of best that you could get in this model year. No air and you got the 3:64 gear and of course dealer added gears were put in for sure. These cars would be a solid 12 second car with the right tires in the back.Even today guys fear coming up against these beasts at the strip.

    Incorrect door panels for 1970, incorrect door panel emblems for 1970 GS

      Shouldn’t it also have the chrome trim plates between the arm rests and the door panels? It’s a Buick for cryin’ out loud, not a Chevy.

      The door panels and emblems looked off to me as well. I thought to myself well maybe it’s just a lower trim level. But now on second thought it seems that I would have seen this before, I have not.

      Any 70 GS 455 owners out there care to chime in and verify further?

        I have a 70 Stage1 but I admit I don’t spend my life understanding every nuance. The door panels look completely different, the fender emblems appear set too far forward, and I believe the chrome Stage1 air cleaner is from a Riviera Stage1 package. I do kind of wonder about authenticity. Also, I wonder how many people who were aware of the Stage1 package, and ordered it, passed over the power disc brake option and simply checked the power brake option, as well as completely passing on the F41 suspension package. Probably happened, but I would look this car over pretty carefully.

    These beasts put fear in the heart of hemi owners. Was as bad as it got in 70. They always sell for less than their GM mates.

    I had a ’70 GS Stage 1 back in the early 80’s. It had Hooker headers, Crane cam, a reworked 800 CFM Q-jet and HEI distributor with an auto trans and 3.42 posi.

    I only ever lost one street race. I was to a big block ’68 Camaro that had nitrous on it. At the time I had never even heard of nitrous. Even then he could only pull me about 2 car lengths to 100 MPH. He was totally shocked at how well my car ran.

    I would love to have another one!

    The GS Stage 1 emblems on the front fenders (especially the driver’s side) at too far forward. Makes me wonder if the car has original paint on it.

    Adjusted for inflation, the $2/gallon gas in my area is 29 cents in 1970 dollars.

      I believe that you are correct, sir. Years later, a magazine – don’t remember which one – had one of these race a hemi car in the 1/4 mile. Both purported to be stock cars and the Buick won.

        It was the cover story in Muscle Car Review.

        Roy Badie’s Hemi Roadrunner versus Ricard Lassister’s GS Stage 1.

        Richard was the president of the GS Club of America. The Buick won the shootout.

    Didn’t all stage ones come with the exhaust cut outs in the rear bumper? Or was that an option?

      No the N25 code through the bumper exhaust was an option in ’71and ’72.

    looks to be an early 1970 build, the door panels, emblems and gauge package with pointed lenses are correct for a bench seat automatic built in 1969. i agree with z28th1s the fender emblems on the drivers side are too far forward

    Definitely a business mans muscle car, a corporate executive could drive this to work, and not break a sweat, and on Saturday night while wifey was sipping Tom Collins and watching Mary Tyler Moore, he could slip out and take in some of the neighborhood youth, then go home strong a d take care of wifey, in her Capri pants

    Perfect color combo for this car. Green is my favorite color and with the clean white interior it just sparkles. I hope to see the price rise above asking. These cars don’t belong in the hands of people who will not protect and maintain them. This is a magnificent car, regardless if all the trim pieces are correct or not. Any and all naysayers should just pass on by, this isn’t the right car for you anyway.
    God bless America
