Queen in the muscle car world, the Challenger was born for the 1970s and was only marketed for four years, during which time it managed to establish itself as a timeless legend. Today, the 1970 and 1971 thousandths are the most sought after by collectors, before American anti-pollution laws spoiled the sporting DNA of the car. The V8 440ci giving some 390 bhp is amongst the most desirable engine available for the range.
