You'll be hard pressed to find a more unique looking vehicle than the Chevrolet SSR (Super Sport Roadster). This retractable hardtop convertible pick up truck was produced from 2003 to 2006 and was inspired by the retro stylings of Chevy's late 1940s Advance Design trucks. The SSR can be found with 3 engine variations, the most powerful of which is the 400 hp LS2 V8.
