Texas man bought this 30-mile Buick GNX for $29,000 in 1987 and it's now sold for an extraordinary amount after changing owners twice

A Buick GNX that cost its original owner just $29,389 has just sold for an extraordinary amount after spending almost 40 years barely being driven.

The 1987 Buick GNX is already one of the rarest and most collectible American performance cars of its era, with just 547 examples ever built.

This particular car is even more unusual because it has only covered 30 miles, meaning it has spent most of its life sitting rather than tearing up the road.

And after changing hands twice in 2024, it has now brought in more than 14 times its original price.

What made the Buick GNX stand out

The Buick GNX was created in 1987 as the ultimate version of Buick’s Grand National, with Buick working alongside ASC/McLaren to turn the already amazing muscle car into something seriously special.

Every GNX came finished in black, with chunky composite wheel arch flares, functional fender vents, a three-piece rear spoiler, and special 16-inch wheels giving it a much more menacing look.

Underneath was a turbocharged 3.8-liter V6 engine paired with a four-speed automatic transmission and rear-wheel drive.

Buick officially rated it at 276 horsepower, although newer testing found that the cars could produce considerably more.

The GNX was also seriously quick for its time, with period testing putting it in the same conversation as some much more exotic performance cars.

This one has barely moved since 1987

The really crazy part is the mileage.

This particular GNX is number 450 of the 547 examples built and shows just 30 miles on its odometer.

It was originally purchased for $29,389 in 1987, with the car retaining its black exterior and two-tone black and Sand Gray interior.

The car also comes with its original manufacturer literature, memorabilia and copies of the 1987 window sticker, while a Carfax report shows no accidents or reported damage.

For a car that’s nearly 40 years old, that’s about as close to a time machine as you can get.

How much it sold for this month

The GNX’s recent ownership history is almost as interesting as its mileage.

According to Bring a Trailer’s auction records, the car sold for $220,000 on July 1, 2024 before changing hands again for $200,000 just nine days later.

It was then offered for sale by a dealer in Carrollton, Texas, in September 2026.

This time, bidding climbed all the way to $427,000, with 57 bids recorded before the auction ended on September 24.

That means its latest selling price is roughly 14.5 times what the original owner paid for it in 1987.

And the buyer didn’t just get an extremely rare Buick with 30 miles on the clock.

They also got a piece of 1980s muscle car history that has somehow spent almost four decades waiting for someone to finally put some miles on it.
