40. Buick GNX
To talk of the 1987 Buick GNX one has to first go back to 1982 with the launch of the Buick Regal Grand National. The Grand National also brought Buick the Manufacturer’s Trophy in the 1981 NASCAR Winston Cup Grand National Series. The GNX featured modifications of the turbo-charged and intercooled 3.8-liter V6 engine used in the Grand National, as well as special wheels and tires, suspension and exhaust system modifications, analog instrument cluster and functional body modifications.
