70 Plymouth Roadrunner with a roaring 440-6 engine. Only 697 of them were produced in 1970 so this beauty with a 4 speed manual transmission is certainly one of the finer examples we've seen in recent years. With power front disc brakes, black leather seating and the factory radio still in place. Excellent Paint/Body Lines with Air Grabber Hood. Vitamin C Orange paint. Overall, this 1970 Plymouth Roadrunner 440 Six Pack is a clean, classy muscle car that has undeniable curb appeal and sensational performance.
