AutoHunter Spotlight: 9k-Mile 1987 Buick GNX

Blacked-out, boosted, and badass


Featured on, the online auction platform driven by, is this 1987 Buick GNX. It is number 209 of 547 produced in collaboration with ASC McLaren and has accrued only 9,280 miles since new. Power comes from a turbocharged 3.8-liter V6 and is sent to the road through a 200R4 four-speed automatic transmission and a limited-slip differential. Features include front and rear spoilers, 16-inch wheels, power windows and locks, power steering, cruise control, air conditioning, GNX-specific gauges, and power front disc brakes. Finished in Black over a black and gray cloth interior, this GNX comes with awards, a window sticker, an owner’s manual, documentation, a Molly Designs jacket, an extra set of wheels and tires, a car cover, a clean CARFAX report, and a clear title in the seller’s name. 

The monochromatic exterior is finished in Black and accented with matching front and rear spoilers and bumpers as well as black trim and mirror caps.  

Like the body, the 16-inch cross-laced aluminum wheels are black but feature polished lips. Those are wrapped in the reportedly original 255/50 Goodyear Eagle VR50 tires.  

Inside, this GNX offers black and gray cloth front bucket and bench rear seats, a leather wrapped steering wheel, and embroidered floor mats. Comfort and convenience features include power windows and locks, power steering, cruise control, a power driver seat, air conditioning, and a Delco AM/FM/cassette stereo with a graphic equalizer. A badge on the passenger side of the dashboard identifies this GNX as number 209 in the production run.

Vehicle information is displayed on a set of GNX-specific Stewart Warner instruments that consists of a 160-mph speedometer, an 8,000-rpm tachometer, and gauges for the coolant temperature, fuel level, boost pressure, and oil pressure. The odometer shows 9,280 miles, which is in line with the 9,232 miles recorded on the CARFAX report in June 2023. 

Under the hood, the 3.8-liter V6 is equipped with a Garrett turbocharger, which has a ceramic impeller and a GNX-branded heat shield, and an intercooler. Official output when new was 276 horsepower and 360 lb-ft of torque. A 200R4 four-speed automatic transmission sends engine power to a limited-slip rear differential. 

Power front disc and rear drum brakes scrub off the speeds the GNX is capable of hitting. GNXs received a modified rear suspension that included a Panhard rod and a longi­tudinal torque bar.  

The auction for this 1987 Buick GNX ends on Monday, July 8, 2024 at 11:45 a.m. (PDT).
