This stunning 1968 Plymouth Road Runner Hardtop Coupe, finished in eye-popping Sassy Grass Green over a clean black vinyl interior, is a highly desirable first-year icon. Power comes from a strong 383ci V8 paired with a dependable 727 Torqueflite automatic transmission, and it features rare factory-installed air conditioning. With only 35,909 miles, this beautifully restored and well-maintained example carries the correct RM21 code, verifying its authenticity.
