The first Grand National(1982) was built by Cars and Concepts in Brighton, Mich., for Buick. Listed for $15,490.00, had a 4.1 liter(N/A) V6, 3.23 axle, GT suspension, and about 215 were made. Buick won the NASCAR Grand National championship in 1981, so they built these to commemorate that event. The first one introduced(Daytona 500, 1982) was Black over silver, and had t-tops. There were 'Sport Regals' that had turbo'd V6s before those, but the turbo'd engines didn't filter into the GNs 'til '82. Nothing in the Buick history books about V8s in any of the GNs. I had an '87 T-Type that was factory with a 5.0(bought it for some of the black out trim, stock alum. wheels, and to use as a guinea pig for my homemade dash).
