The 1987 Buick GNX represents the last and most extreme evolution of the Grand National platform, encapsulating the end of Detroit's muscle car era. Only 547 examples were produced, with car #183 standing out as a meticulously preserved collector-grade item featuring 2,914 original miles. Offered by SBX Cars, it comes with detailed documentation like the original window sticker. The GNX, developed in collaboration with ASC/McLaren, features notable specifications of a 3.8-liter turbocharged V6 producing 276 horsepower and swift acceleration times, making it a significant performance vehicle of its time.
With full documentation from ASC/McLaren, its original window sticker, and complete service records, this GNX represents one of the few remaining opportunities to own a piece of 1980s performance royalty in near-delivery condition.
Working with ASC/McLaren, Buick extracted even more from its 3.8-liter turbocharged V6, tuning it to produce a factory-rated 276 horsepower and a staggering 360 lb-ft of torque at just 2,400 rpm.
