The Buick Grand National was one of the hottest performance cars of the dark days of the 1980s, and its performance is still very respectable even by today's standards.
For the 1986 model year, Buick slotted in the final piece of the Grand National puzzle, by installing a Garrett air-to-air intercooler between the turbocharger and the throttle body, boosting horsepower to 235. For 1987, that package was reprogrammed for 245 horsepower. Intercooling makes the 1986 and 1987 Buick Grand National the ultimate modern Buick performance car and perhaps the most sought-after, regular-production General Motors car of the 1980s.
