General Motors surprised the motor world with the Chevrolet SSR (Super Sport Roadster) pickup truck concept vehicle during the 2000 event. Nostalgic styling and a two-piece retractable hardtop that stowed vertically between the seats and the rear storage bed were crowd pleasers. Based on the S-10 compact pickup, the SSR featured pontoon fenders, retro grille and large round headlights nspired by the 1947-53 Chevrolet trucks.
