1 of 678: 1970 Buick GSX

Between 1970-72, the GSX was the grandaddy of the Gran Sports from that era. They were created to put Buick on par with the high end of the rest of GM’s mid-size performance cars, like the GTO Judge. Production numbers were low, so few were around then and even less so today. This 1970 GSX has been in storage, doesn’t run, and has more than its fair share of rust to be dealt with. Located in Johnsburg, Illinois, this numbers matching machine is available here on craigslist for $65,000 OBO. Thanks, Gunter Kramer, for another rare muscle car sighting!

For its first year, 1970, you could get a GSX painted in any color you wanted as long as it was either yellow or white. The cars had spoilers fore and aft and they wore special emblems. The heart of the GSX was an engine that had the highest torque rating of any American car until the Dodge Viper came along in 2003. It produced 510-lb.ft. of torque at 2,800 rpm and 350hp at 4,600 rpm. And the Stage 1 option would add even more. There were 678 GSX’s built during ‘70 and those finished in yellow with an automatic transmission (like the seller’s car) numbered fewer than half that. This ’70 GSX is not a Stage 1 car.

The GSX was a $1,195 upcharge from the regular GS model. Some of the goodies the buyer got were a hood tachometer, stiffer suspension pieces, heavy-duty cooling, power front disc brakes, and G60x15 tires on Buick Rallye chrome-plated wheels. The seller says his GSX is #308, which we assume is a sequential production number for the cars. Sometimes verifying a GSX as the real deal is hard to do because they had no special VIN, but the seller says this car comes with its build sheet and a Wayne Roberts Report.

We’re told this Buick has been in storage for more than 30 years and – given the amount of rust – we’re guessing a good bit was outdoors in the elements. So, a complete restoration is needed for the non-running car. Supposedly it’s a complete vehicle, but no photos of what’s under the hood are provided. Despite the rust in every piece of sheet metal except for the hood, we’re told the frame and main structure of the car are solid. The hood looks to have come from another car.

Many of the interior pieces will need replacing, the driver’s door no longer latches, and the rear spoiler is not connected, so you’d better take it with you separately. The 1970-72s Buick GSXs can be high-dollar cars, especially the 1970 model. Hagerty estimates one in Concours condition can fetch north of $135,000. But 50% of that value is tied to the asking price of the seller’s rusty car.

    Based on what IS visible, I have a sneaky feeling that the only thing under the carpet is the tarmac. All this for $65k. See Wilma, you CAN have your Kate and Edith too.

    I know it’s a rare car, but seems like long money for a project this big. That said, the GSX is one of my favorite muscle cars of all time.

      The owner must think it’s an old Mopar for that kind of asking price.

    Very, very overpriced. Hemmings has one that appears to be in excellent condition at just over $100K. It would take at least $100K on top of the purchase price to get this one to that level. These are rare, but there are enough of them around that it isn’t necessary to acquiesce to an unreasonable seller.

    Waaaaayyy overpriced! Maybe if it was a white, 4 speed, stage 1 car in this condition and absolutely all the pieces were there, you could consider this asking price. Being the more common Saturn yellow, automatic, missing tach, missing chin spoiler, missing steering wheel (has pontiac wheel) a/c gives it bonus points however it NEEDS EVERYTHING. These are my number 1 on my list and still kick myself for missing out on an Apollo white one but good luck at that price. Hopefully they get more realistic and this rare gem gets saved.

    Sometimes what is presented here is just plain outrageous. This is one of those times. Between corrosion and cannibalism, there is nothing left of this car to work with. 65k? Unbelievable.

      Yup, the insanity continues. I might give him 65 bucks for the cool Pontiac steering wheel though! Looks like the best part on this thing…

    As has been said: way overpriced for what someone would get here. “IF” someone buys this one they’ll be underwater so fast it will make your eyes spin IMO.
    Someone is going to have to really love that car to bite at the asking price.

    If someone really has $65,000 to spend, I’ll be selling a 90% refreshed and stored (40 years ago) non GSX, but highly original, numbers matching, 455 Stage 1, 4 speed, A/C car (only 61 made). 0 rust, original glass, original sheet metal, very clean underside, very nice “3” level driver. etc., etc. Not quite ready yet, but that’s what 65k ought to get you in Buickland.

      Your rationale of VIN swapping is exactly why the asking prices of muscle cars are so high.
      There’s enough fraud out there already.
      The market will drive the price of this one and in the current one $65k is a bit steep for the condition.
      But for some folks it’s all about the hunt……get it road worthy and drive it to the local Cars & Coffee and it would be center of attention for sure.

    “Hey Troy, what kind of Chevelle is that? Is it a Pontiac?” Asked my freind one night cruising in my ’68 death trap special Chevelle back in around ’85.
    “No man, thats a Buick. A fast Buick too, It’s a…”
    ” Buick??? Really?”
    My dad asked the same question in the late nineties about this yellow GTO, or Oldsmobile that drove past his house now and again.
    No dad, that’s a Buick GSX. Its a really fast ca….
    “Buick??? Realy.” His enthusiasm faded even after I convinced him of the cars capabilities. He just wouldn’t believe it.
    So it goes for the teen aged rebel of all Buicks, not the grandaddy just for sake of the old folk brand, ha ha. Rare then, really rare before the second coming of the Muscle car, and now well known and admired. Just not this overpriced neglected delinquent. Tooooo baaad.

    Try calling Mike Wolf from American Pickers! He’s widely known for liking rusty gold! The cost of a body off resto is so cost prohibitive that a potential new owner would be so far underwater, they would have serious negative equity in this project. Maybe a nice parts car and once stripped to a crusher! Remember folks this not a Stage I car.

    I’ve always found the 1970 Buick GSX the best looking car Buick produced. I’ve always found the front end of the car, particularly the grille, more attractive than the standard Skylark.

    I wonder if this car ever sold, and if so, for how much. Correct me if I’m wrong. But I thought the 1970 Cadillac Eldorado had the highest torque rating of that period with 550 lb-ft at 3,000 rpm.

      So…the ratings you speak of are for similar vehicles IN ITS CLASS. The Buick here, does NOT place similarly to the Cadillac Eldo you are referring to.
