Someone Will Pay Six Figures For This 1987 Buick GNX

Despite being over three decades old, the 1987 Buick GNX is still a legend. The era of GM's rear-wheel-drive coupes was about to come to an end and those involved with theBuick Grand Nationalskunkworks project wanted to do something a bit crazy one last time. The GNX, which stands for "Grand National Experimental", was around for one model year only, built in partnership with McLaren Performance Technologies/ASC (not to be mistaken with McLaren Automotive). The GNX came powered by a turbocharged 3.8-liter V6 paired to a four-speed automatic transmission.

Buick actually underrated the coupe's total output at 276 horsepower. In reality, output is 300 hp and 420 lb-ft of torque. Compared to the regular Grand National, the GNX was equipped with a special Garrett T-3 turbocharger, a larger capacity intercooler, and a low-restriction exhaust with dual mufflers. The transmission was also reprogrammed with a custom torque converter and transmission cooler.

Inside, each GNX received a serial number on the dash plaque as well as a unique instrument cluster complete with Stewart-Warner analog gauges, including a turbo boost gauge. Performance? Try a quarter-mile time of 12.7 seconds at 113.1 mph and a 0-60 mph in 4.6 seconds. Amazingly, both times are faster than two of the most epic supercars of the time, the Ferrari F40 and Porsche 930. All told, GM built only 547 examples knowing full well the GNX would be an instant collectible. Needless to say, surviving cars are hard to come by and expensive.

This 202-mile GNX is no exception. 1987 Buick GNX #308 is currently up for sale onBring A Trailerwith a current top bid of $105,000. The auction won't end until Monday, January 20, meaning a bidding war could easily start.
