In the middle 1980s, the fastest production car in America was, for a brief window, not some piece of European exotica; it was a Buick. The Grand National and its big brother, the GNX, were sleeper cars — they looked just like every other G-platform GM car, but packed serious heat under the hood. The GNX variant pushed nearly 300 horses (Buick sandbagged the rating at 276) and over 350 lb-ft of torque. Sixty miles an hour was less than five seconds away. Quarter mile times were similarly impressive.

Of course, being GM products, they mostly all fell apart by the mid to late nineties. Except for one, apparently: Boulevard Buick, in LA’s Signal Hill area, still has an unsold, pristine GNX on the floor; it’s got 167 miles on it, accumulated mostly going to and from the service bay for periodic maintenance.

It is not for sale.
