This car was the fifth GNX off the line.

The 1987 Buick GNX is an emblematic symbol of 1980s performance, and one such model, serial #005 out of the 547 ever produced, has surfaced in New York with a mere 1,800 miles on its odometer. Originally delivered to Buick Mart in Cerritos, California, this GNX exchanged hands via a BaT auction in 2021 before its current dealer acquired it in 2023. Still in pristine condition, the vehicle possesses a clean Carfax report and is accompanied by its original purchase documents, manufacturer’s literature, accessories, and even its window sticker.

Created in collaboration with McLaren Performance Technologies/ASC, the Grand National Experimental was a swan song, marking the end of this particular production line. Characteristic of the GNX are its heat-extracting fender vents, composite wheel arch flares, tri-piece rear spoiler, and the GNX badge. All units ever produced sported a black (19U) finish. This particular GNX underwent a bumper filler replacement at some point in its life. The GNX rides on 16-inch cross-lace wheels adorned with GNX-branded center caps. Yokohama YK420 tires wrap these wheels, with sizes 245/50 at the front and 255/50 at the rear.

Step inside, and you're welcomed by front bucket seats and a rear bench, all draped in a black and Sand Gray cloth combo. A "Turbo 6" embroidery graces the front seat headrests. A plaque, identifying this as GNX #005, is prominently placed on the passenger side of the dashboard. Modern comforts aren't amiss – it boasts power-adjustable driver seats, air conditioning, cruise control, power windows, and door locks. Music enthusiasts will appreciate the GM-Delco Concert Sound AM/FM/cassette radio equipped with a graphic equalizer. Recent refurbishments include the replacement of the headliner and heater core, with the air conditioning system also receiving service.

Powering this beast is a 3.8-liter V6 engine, tweaked by ASC/McLaren. It houses a Garrett T3 turbocharger protected under a GNX-branded heat shield. Thanks to these modifications, and more, the engine churns out an impressive 276 horsepower and 360 lb-ft of torque. This power is effectively transferred to the rear wheels via a Turbo-Hydramatic 200-4R four-speed automatic transmission, which also boasts a factory-enhanced oil cooler.

With its authentic blend of classic beauty and modern touches, the 1987 Buick GNX remains a prized possession for car aficionados. At a total initial price of $29,389, this specific GNX is a testament to Buick's unmatched legacy and is sure to fetch attention and admiration wherever it goes. is a top-seller on Bring A Trailer with over 1,000 vehicles listed.
