The Story
Buick ended the Grand National with the GNX, a 547-car run finished by McLaren Performance Technologies with a bigger turbo, a ceramic-impeller, a revised intercooler, a Panhard rod and flared arches over black mesh wheels. Officially 276bhp. In reality closer to 300, and quick enough in 1987 to beat a Corvette, a Countach and most of the road-test establishment. This is a low-mileage, numbered example in factory condition with the build documentation and original delivery paperwork.
