One Family Owned: 1970 Buick GS 455 Stage 1

Disclosure: This site may receive compensation from some link clicks and purchases.

Although the muscle car wasn’t dead by the turn of the 1970s, diminishing sales numbers and impending legislative changes meant the end was in sight for the breed. However, there were still legends rolling off production lines, including the 1970 Buick GS 455. It offered excellent performance, but our feature car ramps that up as a Stage 1 version. It has been part of the same family since the day it left the showroom floor, but it is time for this solid and unmolested survivor to find a new family to protect and preserve it. The seller has listed it here on eBay in Folsom, California. The bidding has raced past the reserve and sits at $28,600.

Enthusiasts seeking a rock-solid restoration candidate that is unmolested may struggle to look beyond this Buick. It has spent its life in its current location, and the favorable climate has preserved its steel nicely. The seller admits there is pitting on the inside of the trunk pan courtesy of a leaking seal, but it hasn’t deteriorated to penetrating rust. Therefore, treating it now means the car’s underside will remain original and structurally sound. A few small spots are visible on the lower rear quarter panels, but these appear patchable. I spotted what looks like pinholes developing in the lower front fenders, although tackling those should be straightforward. The Glacier White paint has its share of imperfections. However, it may prove acceptable following a polish if the new owner pursues preservation over restoration. The grille is damaged, but the remaining trim would only require attention if the winning bidder seeks perfection in their build. The GS rolls on its original wheels, and I can’t spot any glass issues.

The 1970 GS 455 possessed genuine performance credentials, but the Stage 1 version took those to a higher level. This is one of those cars, and while the “base” GS produced 350hp, the Stage 1 placed an official 360hp and 510 ft/lbs of torque under the driver’s right foot. There has often been conjecture about the power figure because Buick regularly pulled engines from the line for testing. One of the Development Engineers recalls that of the fifteen engines tested, the least powerful produced 376hp. This car’s numbers-matching 455 sends its power to the rear wheels via a three-speed TH-400 automatic transmission, with power assistance for the steering and brakes part of the package. The GS 455 left no doubts surrounding its performance credentials once the driver floored the gas pedal. The journey down the ¼-mile took 14.6 seconds, which could never be described as slow. The seller indicates this classic runs and drives, although it is unclear whether it is roadworthy. They include some fresh air cleaner decals and new foam for the Ram Air intake. As with the exterior, the winning bidder must choose between preserving this aspect of the car or pulling the engine to detail everything as part of a high-end build.

This Buick’s seats wear aftermarket covers, but they represent the only interior change or modification. The photos are inconclusive but appear to support the seller’s claim that the dash and pad are in good order. The carpet might respond to a deep clean, but budgeting for replacing it, the cracked wheel, and the faux woodgrain would be wise. The remaining upholstered surfaces look good for their age, while the new owner receives air conditioning, bucket seats, a console, an AM radio, and a tilt wheel.

So, preservation or restoration? Which would you choose if you found this 1970 Buick GS 455 Stage 1 in your workshop? Whatever your approach, you must compete with the ten people who have submitted thirty-five bids if it is to become a reality. Are you prepared to do that? I would hardly blame you if you did.

    Torque is king and what starts these underdogs in motion. Set up properly these wheel standing beasts will best about anything beside them naturally aspirated on a 1/4 mile track. Best part is Buick was the gentleman’s muscle car. Went to school with a Buick guy well known in the Buick circle today, great cars.

        I know both owners of those cars, and while it shows the outcome of how both those cars ran 10 years ago, it’s not truly representative of the famed Buick vs.Hemi rivalry. BTW, the Buick ran 11.8’s before it was retired and the Dodge still shows up at this race and makes one run in the 11.4’s , immediately disqualifying itself.

    These were the true sleepers of their time. The problem was that the rear-end is so light… My mother had a ’71 Skylark Custom Convertible with a 350 in it. I used to light up the tires just by stepping on the gas pedal, much to the joy of my friends! Same held true for my father’s ’68 Firebird. He used to put furnase grates in the trunk for the winter…

    There’s many great reasons why 10 bidders have taken this Buick to almost 30 G’s already. Charlie is right, “these were the true sleepers of their time”. Along with their brothers at Oldsmobile in 1970. My uncle had a Buick wagon w/455 in it back then. Just raw awesomeness.

    I bought a 70 Stage 1 in 79 for $600, was smoking when warmed up and the paint was tires. Not knowing how these cars would appreciate in 30 or 40 yrs, and people would rescue them as rusty buckets from junkyards and make money on them, I am sorry to say I parted this one out. Kept the engine, gave the Ram air hood to my brother in law for his Skylark as well as the tachometer. Who woulda known.

    Street race in the late 60s early 70s. Had a 66 Mustang was doing 12 6 and a quarter. Ran up against one of these guys at a light, by the time I hit 3rd he passed me like I was standing still. Bad part was even that his wife and kids in the car.

    Love this car but definitely would like to see some pictures of the underside. Rust in lots of places in the pictures provided. Some suggestions that it could extend deeper (e.g., the metal patch(?) on the floor in front of the gas pedal).

    This is the kind of Buick that you dream of finding. If the disto, carb and all #’s match, this is the perfect resto candidate if you have the financial means. However, if it were mine, I’d tackle the drivetrain and suspension, get some new seat covers, carpet and any other interior trim that needs redone and purchase some high quality refinishing products and see how much I could bring that glacier white paint back to life. I like restored cars as much as the next guy or gal, but as I have gotten a little older, something about these true survivor cars that interest me so much more than a concourse restored car. This is a really solid Buick no matter which path of action the new owner wishes to pursue.

    I ordered a 1970 GS 455 Stage 1 with a four-speed and not much else except $75 special-order paint in 1964 Corvette Daytona Blue Iridescent so the steering wheel in this car is curious as mine had a three-spoke brushed metal wheel.

      A three-spoke sport wheel was an option in 1971. Maybe they introduced it at the end of the 1970 model year?

    510 lbs-ft of torque – Isn’t that the reason this car is reputed to have walked a Hemi Charger? Bidding seems to indicate that more than a few people know what this is.

    If I had the cash this would be in my garage in a heartbeat. My first car as 16 year old was a sea mist green with brown leather and auto on the floor back in 1974 . I lost my first year’s license 3 times driving that beast . Like a fool I traded it in on a Chevy nova . At Marty rip Chevy in Monroe Wisconsin. I’ve tried to find it many times, no luck .

    I’m an old timer here. I worked overnight at a Ford Dealer cleaning used cars and getting new ones prepped for delivery before the mechanics would do a final inspection. We had a couple of these come in…….. real sleepers! No loud exhaust like hooker headers or thrush, but stomp on it and it would light them up! This one is looks to be a time capsule. Buick made this a quiet screamer. A great car! AND they did it again in 86/87 with the Grand National and GNX. This car is historically significant! Good luck to the new owner!!

    In 78 a friend was left one of these, by of all people, his grandmother! Beautiful, powerful car. Unfortunately, his immaturity, coupled with such power, quickly led to the inevitable – within 3 months he wrapped it around a tree on a winding road just 2 blocks from his home. He and his girlfriend were both killed, and, of course, the car was destroyed. 8 years later his father shot and killed his mother, then himself. He’d never gotten over losing his son. A profoundly sad situation all around. With that being said, I’d still love to have one of these, but any color other than white.

    I too am oldie guy. Bought one from a coworker in 1972. It was a 1970 stage one, loaded up, but best of all it was black on black, on black! Was a stunning combination. Back then cars were just cars! Loaded it up with our gear and took it camping all summer long. Had the custom package, the spoke wheel, bucket seats, console, etc. Paid $2,200.00 for her and sold it for $2,900.00 if I remember correctly. In My opinion one of the best s signs ever.

    Oh no, now this actually brings back a not so great memory. Sadly I actually tore the entire nose off of one of these back in 1988. The guy driving it had stolen it from his girlfriend’s dad. He himself an army deserter. Well no money , thirsty car, decided to steal gas. As he was pulling out of the gas station he floored it. And luck would have it, there go I in a 1976 country squire Ford. Smack boom crash. Yeah you get the whole picture. Not proud of it mind you but those big engines saved lives. But the entire front clip of the Buick was gone. Literally ripped off the car. Both cars totalled. Stupid part is I got into more trouble for going to the movies in the city that night than he did. Not sure entirely to him I know the Army dropped the charges and dishonorable discharge, a couple years in the state pen. But I had to go tell my parents what happened to their car. Let’s just say I had no fun. Anyway the last I saw of the Buick was its real owner picking up the remaining pieces from the impound lot on a roll back. I never felt so bad for someone over a car in my life as I did right then. Guy had tears. Anyway that’s the take of a 400 Ford taking out a Goliath 455
