Do you remember that pristine 1987 Buick GNX we showed you last week? Well, the limited-edition Buick recently sold for an extraordinary $200,000 on Bring A Trailer.

The automaker only made 547 examples of the Buick GNX during the car’s single year in production. Co-developed with McLaren Performance Technologies/ASC, the Grand National Experimental may not look all that special to the uninitiated, but it has become very desirable in recent years. The last one ever made sold for $220,000 a couple of years ago with 68 miles (109 km) on the clock.

The 1987 Buick GNX sold on BAT was number 480 and originally sold new by Ralph’s Buick in Arkansas. Shortly afterwards, the car was put on display at a Texas dealership and has never turned a wheel under its own power since. The clock stopped at just 8 miles.

As if that wasn’t enough, the GNX retains the original protective plastic over the front seats and door panels. There’s also sheets of plastic covering the black carpeting and the floor mats have been stored in the vehicle’s trunk all these years.

Powering the Buick GNX is a 3.8-liter V6 upgraded with the help of McLaren Performance Technologies/ASC. Alterations made include a new Garrett T3 turbocharger, enlarged intercooler, and a low-restriction exhaust that helps lift power to 300 hp when new. Mated to this engine is a Hydramatic 200-4R four-speed transmission with an enlarged oil cooler. The GNX could run the quarter mile in a respectable 12.7 seconds at 113.1 mph (182 km/h).

The person who handed over $200,000 for the car also received the car’s original sticker, owner’s manual, warranty booklet, and a clean Wisconsin title in the seller’s name.

We’re intrigued to see how high GNX prices go in the coming years.
