3. 1970 Plymouth Roadrunner 426 Hemi

The 1970 Plymouth Roadrunner featured updated front and rear end looks compared to the 1968 model. Updates included a new grille, a cloth & vinyl bench seat, hood, front fenders, quarter panels, single-piston Kelsey-Hayes disc brakes, and even non-functional scoops in the rear quarters. The air grabber option on the front scoop featured a switch that would cause a vacuum servo to slowly raise the scoop to expose shark-like teeth on either side. Due to insurance companies adding surcharges to muscle car policies, sales for the Roadrunner dropped by more than 50 percent. A very rare version of the Roadrunner, a convertible equipped with the 426 Hemi was sold. Only three of these were sold in America and 1 in Canada.
