This 1987 Buick GNX, the 450th out of a limited run of 547 units produced in that year, currently displays just 26 miles on its odometer. It has been meticulously preserved in long-term storage by its previous owner and has remained there since being acquired by the current owner in 2013.

Fully Loaded For Speed

The vehicle boasts a turbocharged 3.8-liter V6 engine coupled with a four-speed automatic transmission. It features the infamous black exterior with a two-tone black and Sand Gray interior. The GNX is equipped with a limited-slip differential, 16-inch cross-lace wheels, composite wheel arch flares, fender vents, and a rear spoiler. Currently listed on Bring A Trailer, it’s available through dealer consignment, with a clean California title.

Heavy Duty Suspension

The GNX’s suspension system incorporates components from the contemporary Regal for the front, while the rear setup is enhanced with a Panhard bar, torque arm, and an additional frame crossmember for improved stability. Braking is managed by power-assisted front disc brakes and rear drum brakes.

Inside The Cabin

Inside, the cabin is adorned with black and Sand Gray cloth upholstery, with the front bucket seats and rear bench featuring Turbo 6 embroidery on the headrests. The interior is also equipped with a power-adjustable driver’s seat, power windows, and a Delco cassette stereo complete with a graphic equalizer. A dashboard plaque on the passenger side proudly denotes this vehicle as GNX #450.

The driver is greeted by a leather-wrapped steering wheel and GNX-specific Stewart-Warner gauges, including a 160-mph speedometer, an 8,000-rpm tachometer, and additional dials for boost, oil pressure, coolant temperature, and fuel level. The five-digit odometer indicates 26 miles, with only a few miles added by the current owner.

Turbo GO!

Under the hood, the 3.8-liter V6 engine has been enhanced by ASC/McLaren with a Garrett T3 turbocharger. The mill is protected by a heat shield bearing the GNX emblem, a larger air-to-air intercooler, and a low-restriction exhaust system. The engine’s output was officially rated at 276 horsepower and 360 lb-ft of torque. An oil change has been recently completed in anticipation of the sale. The power is delivered to the rear wheels via a 200R4 four-speed automatic transmission equipped with an upgraded oil cooler, and the differential is crowned with a GNX-branded aluminum cover.

Fat Wallet Required

It was said that the GNX was faster than a Corvette back in 1987. Today this is a red-hot classic with a cult following. Along with the trailer, bring lots of money as the current bid is $150,000.
