1987 Buick GNX sold for $200,000; two years and 4 miles later, it fetched $427,000

In July 2024, a 1987 Buick GNX with only 26 miles on the odometer was listed for sale on Bring A Trailer for $200,000. Two years and four additional miles later, the same car was sold for $427,000, according to an online report by Bring A Trailer. This remarkable increase in value highlights the high demand for well-preserved examples of this iconic American performance car.

Built as a limited-run celebration of the Grand National era, only 547 GNX models were produced, all in black, and each with distinctive McLaren and ASC performance upgrades. The car's turbocharged 3.8-liter V6 engine, upgraded suspension, and limited-slip rear differential combine to create a machine that remains highly sought after by collectors.

With its clean Carfax report, original window sticker, and California title, the latest owner is offering the nearly untouched vehicle as a rare glimpse into the golden age of American performance cars.
