Since American “big-block” V-8s were largely extinct by the mid-1970s, Buick engineers experimented with turbocharging the 231-cubic inch V-6, and their first high-profile effort, a 307-hp Century in 1976, was the first V-6-powered Indianapolis 500 pace car. The chiseled lines of the new-for-1978 Regal helped Buick take the NASCAR manufacturer’s title for 1981 and 1982, and to celebrate, the first Grand National Regal appeared in 1982.

The option returned in 1984, now only with a turbocharged V-6 engine, an all-black exterior, aluminum wheels, special seats, high-performance underpinnings and unique badges. Steady development and intercooling raised output to 245-hp by 1986, creating America’s quickest production car. As Grand National production neared the end, Buick authorized a limited run of 547 specials, designated GNX. Built by ASC/McLaren, the builders of the 24-valve Buick turbo V-6 engines for Indy, the GNX used a high-performance Garrett turbo, an improved intercooler, revised engine and transmission calibration and lower-restriction exhaust. Output jumped to over 276-hp with 360 ft-lbs torque. Larger tires, special alloy wheels, a rear-axle torque arm and a Panhard bar plus a stiffer frame were GNX-specific upgrades. Front-fender vents and special analog instruments completed the package, which also included a full load of factory options.

This very special GNX has never been road-registered and shows approximately 150 miles from new. Remaining in “time warp” like-new condition, it still carries its original window sticker in the window and has just been titled for the first time to be sold at this auction. Garage kept and properly maintained in climate controlled storage this is an excellent opportunity for a discerning collector to purchase one of the lowest mileage examples in existence.
