In 1978, Buick introduced the Buick Regal turbo that became the Grand National and produced it through 1987. By 1987 the car manufacturer had equipped the original front-engine, rear-wheel drive cars with intercooled, turbocharged 245-horsepower V-6 engines as standard equipment. A Grand National can go from zero to 60 miles per hour in about 6.9 seconds or less, with an official top speed of 124 miles per hour.
In the final model year, Buick offered a GNX version of its Regal Grand National. The car maker only manufactured about 500 GNX cars, and the sticker price was in the $26,000 to $29,000 range. Equipped with Stewart-Warner gauges, higher horsepower and custom features, the GNX officially can reach 60 miles per hour in about 5.4 seconds, and 104 miles per hour in 13.4 seconds or less.
