A practically new 1987 Buick GNX will cross the block at a Barrett-Jackson auction on June 19th. After all these years, the charged muscle car only has 8.7 miles on the clock, according to the auctioneer.

Abbreviation for Grand National Experimental, the GNX was a one-year graduation special for the Buick Grand National that was developed in collaboration with McLaren Performance Technologies / ASC (an American company not related to the British automaker and racing team). The car up for auction is number 480 of 547 cars built for the GNX’s only model year.

Like the standard Grand National, the GNX was equipped with a supercharged 3.8 liter V-6 engine. In the GNX, the V-6 put out 276 horsepower and 360 pound-feet of torque, delivering a claimed 0-60 mph in 4.6 seconds and a 12.7 second quarter mile. That was faster than a Ferrari F40.

The V-6 was equipped with a 4-speed automatic transmission with rear-wheel drive. The Grand National and GNX were discontinued because the Buick Regal, on which the performance models were based, was to be converted to a front-wheel drive platform for the 1988 model year. Buick tried performance versions of some front-wheel drive models, but with disappointing results.

This car was originally sold by Ralph’s Buick in Mena, Arkansas and then exhibited by a Texas company. According to the listing, it was then parked in an environmentally controlled exhibition area and has not been driven since then. The same car sold for $ 200,000 at Bring a Trailer in 2019.

Interestingly, this isn’t the only practically new GNX that has appeared in recent years. An unsold GNX with only 202 miles was listed on Bring a Trailer last year and also appeared in Jay Leno’s garage. By comparison, the first GNX sold to the public (number three out of 547) had 10,790 miles when it went on sale in 2017.
