The Buick Grand National Experimental was created in partnership with ASC/McLaren to celebrate the end of the vehicle’s production run. All 547 examples were finished in black, and details specific to the GNX include a three-piece rear spoiler, composite wheel arch flares, heat-extracting fender vents, and GNX badging. Additional exterior details include an automatic power antenna, a rear window defogger, and sport mirrors. Aftermarket window tint film has been applied to the rear and side windows.
Factory 16″ basketweave wheels feature GNX-branded center caps along with chrome trim rings and are wrapped in Goodyear Eagle VR50 tires measuring 245/50 up front and 255/50 out back. The GNX features front suspension components from the contemporary Grand National, and upgraded rear components consisting of a Panhard rod and torque arm and an additional frame crossmember. Braking is handled by power-assisted front discs and rear drums.
The cabin features bucket seats upholstered in black and Sand Gray cloth, and the front headrests feature embroidered Turbo 6 logos. Additional amenities include a power-adjustable driver’s seat, air conditioning, cruise control, and a Delco AM/FM cassette stereo with a graphic equalizer. A plaque mounted to the passenger-side dashboard identifies this as car #114 and can be seen in the gallery below. The selling dealer notes that the headliner is sagging.
The leather-wrapped steering wheel frames GNX-specific Stewart Warner instrumentation consisting of a 160-mph speedometer, a tachometer, and gauges for boost pressure, oil pressure, coolant temperature, and fuel level. The five-digit mechanical odometer shows 759 miles.
The GNX features an ASC/McLaren-modified 3.8-liter V6 which is equipped with a Garrett T3 turbocharger under a heat shield with GNX lettering as well as a larger air-to-air intercooler and a low-restriction exhaust system. Factory-rated output was 276 horsepower and 360 lb-ft of torque. The selling dealer notes that the battery was replaced and an oil change was performed in preparation for the sale.
Power is sent to the rear wheels through a TH200-4R four-speed automatic transmission with a factory-upgraded oil cooler and a limited-slip differential that features a GNX-branded aluminum rear cover.
The window sticker lists initial delivery to Stitzer Buick-GMC in Indianapolis, Indiana, as well as standard and GNX-specific equipment and a total manufacturer’s suggested retail price of $29,290. A certificate of origin, manufacturer’s literature, and warranty information are also included in the sale along with a GNX book, jacket, and hat.
