9,258-mile Buick GNX 3.8L Turbo Charged V6 Automatic A/C Documented.
The pinnacle in the GM Buick lineup came in 1987 with a limited-edition, specially prepared, Grand National Experimental or GNX-the ultimate development in American muscle at that time.
A total of just 547 cars were built by Buick with a Grand National interior and then sent to American Specialty Cars (ASC) McLaren Performance Technologies for the GNX transformation.
Improvements included a Garrett T3 turbocharger with ceramic impeller and GNX heat shield, larger capacity intercooler, reprogrammed engine management and performance suspension with torque bar and GNX-only rear differential cover.
The 3.8L V6 engine in the GNX was conservatively rated for 300 horsepower at 4,400 RPM and 360 lb.-ft of torque at 3,000 RPM and backed by a specially prepared Turbo-HydraMatic 2004R transmission.
The GNX will launch from 0-60 MPH in under five seconds and run a low 13-second-quarter mile.
The sinister exterior featured vented fenders, a distinct lack of hood and fender emblems, and 16-inch aluminum mesh wheels with black-out face and GNX center caps. Special composite fender flares were fitted to the wheel wells to make room for the beefy wheels and tires, as well as making the car more recognizable.
This unrestored GNX is number 459 of the 547 produced and shows an astonishingly low 9,258 miles on the odometer in the special instrumentation package.
The car comes with GNX ASC McLaren letter, broadcast sheet and window sticker which list everything that makes this turbo Buick a Grand National Experimental.
