Fast Facts: Plymouth Road Runner

The family of Plymouth Road Runner models is one of the most recognizable sets of muscle cars we can think of. That’s not the only thing that sets them apart, though. The Road Runners were known for being inexpensive, unique and quirky in a way that made them lovable. That quirkiness came from the famous Warner Bros. cartoon and the famous “beep-beep” noise that would become one of the vehicle’s most memorable features.
