PlymouthRoad Runner

The Plymouth Road Runner is a muscle car introduced by Chrysler in the United States for the 1968 model year and marketed under its Plymouth brand. Initially based on the Belvedere, the brand's basic mid-size model, the Road Runner combined a powerful engine with a spartan trim level and a price that undercut increasingly upscale and expensive muscle cars such as the Pontiac GTO and Plymouth's own GTX. It was initially a sales success.
