The Buick Grand National Experimental or GNX was a limited-edition, specially prepared vehicle that was identifiable as future collectibles when they were new. By 1987, the turbocharged 231 CID V-6 engine offered over 245 horsepower, while a stock 305 CID V8 in an automatic-equipped Camaro developed just 190 horsepower.

A total of just 547 cars were built by Buick with a Grand National interior and then sent to American Specialty Cars (ASC) McLaren Performance Technologies for the GNX transformation. Improvements to the cars included a Garrett T3 turbocharger with ceramic impeller and GNX heat shield, larger capacity intercooler, reprogrammed engine management and performance suspension with torque bar and GNX-only rear differential cover. The 3.8-liter V6 engine in the GNX was conservatively rated at 276 horsepower and 360 lb-ft of torque and backed by a prepared Turbo Hydra-Matic 2004R transmission.

The Buick GNX could race from zero-to-sixty MPH in under five seconds and could run the quarter-mile in the low 13-seconds. Exterior features included vented fenders, a distinct lack of hood and fender emblems, and 16-inch aluminum mesh wheels with black-out face and GNX center caps, which are equipped with Goodyear Eagle Gatorback tires.

This particular GNX is an unrestored example and number 155 of the 547 produced. The odometer shows just 12 miles.

This car has the GNX-badged front carpet savers, six-way power adjustable driver seat, and the ASC McLaren GNX window sticker.
