AUCTION: 26-Mile 1987 Buick GNX

The Ultimate Low-Mile Buick GNX Is Up For Grabs...

A pristine example of automotive history has surfaced on—a 1987 Buick GNX, No. 450 out of a limited production run of 547 units. This particular GNX has remarkably accumulated just 26 miles since it rolled off the assembly line, spending most of its life in storage until its current owner acquired it in 2013.

A Special Edition with Unique Features –

The Buick GNX, or Grand National Experimental, was developed in collaboration with McLaren Performance Technologies/ASC to commemorate the conclusion of the Grand National’s production. All 547 GNXs were finished in sleek black, distinguishing them with heat-extracting fender vents, composite wheel arch flares, and a distinctive three-piece rear spoiler. This car also features GNX badging throughout, further setting it apart from its Grand National counterpart.

Impressive Mechanical Specifications –

The powertrain, enhanced by ASC/McLaren, boasts 276 horsepower and 360 lb-ft of torque, making it a potent performer even by today’s standards. Noteworthy upgrades include a larger intercooler and a low-restriction exhaust system, all meticulously preserved over the years.
