The supercharged Buick GNX was the hottest American-built performance car you buy in North America in 1987, so it’s no surprise that many buyers opted to stash them away, rather than drive them.

Those cars frequently crop up for sale, often showing little sign of use and displaying under 10,000 miles (16,100 km) on their odometers. But this car is something else. Car number 414 of a total production run of only 547 car has covered only nine miles (15 km) since 1987.

Yes, you read that correct; not 9,000 miles, or 900 miles, or even 90 miles, but nine miles. It was apparently parked up by its original owner in 1987 and never used. That owner passed away and the car’s current seller, Lee Polsky of New Jersey-based King of Cars and Trucks, got his hands on the car last week after a year of waiting, which involved selling some of the owner’s other cars that were blocking access to the GNX, including a 440 Six-Pack Plymouth Road Runner.

The pictures accompanying the listing aren’t great, but they’re interesting because they show the car in its as-found condition, in a garage and covered in a sheet, but also junk. The window sticker is still present and actually affixed to the window, and the protective coverings on the seats, steering wheel, door panels and carpets are there, just as they would have been when the car was delivered to the Buick dealer in 1987.

It’s hard to gauge the condition of the exterior paint from the images, but Polsky told us by phone that the GNX is in excellent condition, bar a couple of minor marks. There’s some chip guard coating missing from the passenger side sill/rocker panel, and a small scratch on the rear quarter, both of which could be easily fixed. Even the original 1987 tires still held air, though after sitting for more than three decades they’re probably a similar shape to an Audi RS steering wheel.

The mechanics, fortunately, are in better shape than the tires. Polsky says the Buick’s 276hp (280 PS) 3.8-liter turbocharged V6 was serviced after being rescued from its hibernation and fired straight up, though it’s got a way to go before its sufficiently run-in to allow the next owner to test out its 4.7-second zero to 60 mph (97 km/h) capabilities.

Unsurprisingly, the Buick has created plenty of interest, despite only relatively recently going live on eBay. With six days of the auction still to go at the time of writing, bids are up to $180,300, with a note in the description suggesting Polsky would pull the listing for a $349,000 offer.

It will surely shatter previous sale records

Will bidding reach those heights? Possibly. An 865-mile (1,392 km) GNX sold earlier this year for $225,000, and last year a 759-mile (1,222 km) example changed hands for $236,000. Coincidently, there’s currently a 203-mile (327 km) GNX up for auction on the Bring-a-Trailer website. Bidding for that car stands at $180,000 with only one day remaining. By ordinary standards that car would appear like a real freaky find, but next to this latest car, it might as well be showing intergalactic starship mileage.

Incredibly, Bring-a-Trailer did once facilitate the sale of a GNX with even fewer miles than today’s barn find. Back in February 2019 an immaculate example with just 8 miles (5 km) sold for $200,000. But that was over three years ago, and we all know what’s happened to classic car prices in that period.

The Buick’s intact original window sticker shows an MSRP of $29,290 in 1987, which in today’s money according to the U.S. inflation calculator, is equal to $74,128

A better guide to this car’s value comes in the form of the nine-mile GNX sold at Barrett-Jackson‘s June 2021 Las Vegas event. That car was also covered in its factory plastic wrap, had been stored in a climate-controlled environments and sold for $275,000. But a year on, Polksy believes his car will sell for more. “I’ve had several offers from around the world already,” he told us. “I think this one is going to set a new record, and the price is going to start with the ‘three’.”

Would you pay $349,000 to buy a totally unused GNX, and would you leave it as found, or sacrifice the originality to have the exterior professionally restored to correct any wear and damage from years of storage? Leave a comment and let us know.
