Stored 40 Years: Rare 1970 Buick GS 455 Convertible

While Buick built just over 20,000 Gran Sports in 1970, the convertible was hard to find when new. Just 1,416 droptops left the factory of which only 232 had the Stage 1 option. The seller bought this garage find from the original owner who had parked it in 1984. The 40 years have taken their toll, and a restoration is needed, including the big-block V8 which is stuck. Located in West Jordan, Utah, this car comes with a rather extensive detailing of what you’ll find and is available here on eBay where $15,600 is the magic number so far (no reserve).

As the story goes, a couple in Oregon bought this convertible new when a move to Arizona was pending. Once they got there, they realized AZ is a hot place and they had the dealer install air conditioning (under-the-dash unit). 14 years and a divorce later, the lady owner parked it in her garage in Tempe and left it there untouched for the next four decades. The seller has tried to get the motor to move, but it’s locked and won’t budge. The tires were rotted, so four new or newer rubber donuts were added.

While this Buick is in somewhat rough shape now, being a one-owner car with a numbers-matching drivetrain increases the likelihood that someone will put the time and money into it to restore the GS to its former glory. Rust is almost non-existent, and the body is straight, so your body man won’t get rich off renewing this vehicle. The interior is worn out from the passage of time and the Arizona heat, so your upholstery guy will get a smile on his face when this one gets dropped off.

Besides a modest restyle, the 1970 Buick GS gained a 455 cubic inch engine in place of a 400 from the year before. Before the vehicle was retired, the seller was told the car received no major work or preparation. It did get a repaint back in the day (due to the relentless sun) and the convertible top is now the see-through variety. The windshield will need to be replaced. Besides being a rare car, the buyer is going to get all the documentation that the original owner kept all these years.

    Looks like quite the find. This one should/will get a resto, so some lucky new owner be very happy

      Sold my 70 GS, Stage 1, 4spd, 3 years ago, that was my 3rd, always loved the GS. Not a big fan of convertibles, but the price is pretty reasonable

    Rare one there and it’s already up there as a non-runner but it’s nice.

    Apparently ebay is back to their charge-by-the-paragraph pricing schedule.

    A seller well steeped in James Joyce should really own a white Roils Royce.

    I love the Buick GS, it might be the most underrated muscle car ever. And this being a convertible with documentation makes this definitely worth restoring. But it’ll take at least double the purchase price to get this show worthy.

    In 79’ I took my cousin Christmas shopping in her and her boyfriend GS 455 and damn she wouldn’t let me hit it down. If I tried she screamed like someone was killing her. It was nice.

    just a base ragtop 455 car. no AC, no buckets/column shift, no gages, AM radio,sunburned and stuck. great project but a biggy. I’d put the underdash AC in my ’64 465 inch special, but otherwise???

    Cheap solid rust free car and a real GS. Most underrated muscle car ever.

    I find this comment in the write up amusing. Being in the body shop business almost 40 years, I know there are no “rich” bodymen. LOL!

      The rarity of this numbers matching animal is the deciding factor regardless of configuration. Like William said it’s basically a meat and potatoes car but it is so rare .

    That aftermarket A/C. The spare tire cover. The Sonomatic Radio. So many little things that trigger memories with my GS back in the seventies
    It’s up over $21k now with three days left. I’m not sure people realize how much it will cost to bring it back to a nice restoration (even if it’s numbers matching)
    Nice if you can afford it. At this stage of my life I couldn’t justify it.
    I’ve been watching this for a few days just for nostalgia

    I’m not terribley familiar with hot rod Buick’s, but I do know that the Stage 1 GS 455 was something of a street sweeper at the time. A friend of mine had a 65 GTO 6 barrel and got blasted by one. Might be spendy to freshen it up, but would seem to me like money well spent.
