9. 1970 Plymouth Roadrunner Hemi Convertible
When it first appeared in 1968, the Plymouth Roadrunner proved to be an influential and important muscle car. Not only did it introduce a new trend of wallet-friendly, yet fun cars, it was also a strong seller that affected the entire market. The whole idea behind the Roadrunner was simple: present an inexpensive yet powerful model and add a crazy name and graphics to attract people on a limited budget mixed with a strong need for performance.
The Roadrunner had a bench seat and manual steering and didn’t have any luxury options, but it came with a powerful 383 V8 as the base engine. Buyers could also opt for a 440 or the mythical Hemi 426. In 1969, Roadrunner got a convertible option for those buyers who wanted an open-air driving feel, but most Roadrunners were two-door hardtops. In 1970, Roadrunner got a mild restyling with a new front and rear end, but the convertible option remained. For just above $3,000, you could be the proud owner of an open-top Roadrunner in 1970. However, if you wanted a few options and a Hemi engine, the price would quickly rise to over $4,000. This was one of the main reasons Plymouth built only four Roadrunner Hemi convertibles in 1970, making it one of the rarest muscle cars and a valuable part of Mopar muscle history.
