Plymouth Hemi Cuda Convertible – $2 to 4 million
Two of the biggest Chrysler legends from the classic days of muscle car culture are the Barracuda and the 426 Hemi engine. And all through the ’60s, those icons of the industry didn’t mix, at least not in street-legal cars. In 1970 Plymouth offered this legendary engine in Barracuda body style, immediately creating one of the fastest and most desirable muscle cars ever made (via Hemmings).
The mighty Hemi engine was an expensive top-of-the-line option for 1970 and 1971, available in coupe or convertible form. It cost around $900 over the price of the standard Barracuda, and it went in just about 600 coupes and only 17 convertibles during a two-year production period. Well, prices for those 17 cars range from 2 to a staggering 4 million dollars.
