5. Plymouth Hemi Cuda Convertible – $2 to 4 Million
Two of the biggest Chrysler legends from the classic days of the 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. So in 1970, Plymouth offered this legendary engine in Barracuda body style. And immediately, they created one of the fastest, most desirable muscle cars the car industry ever made.
The mighty Hemi engine was an expensive top-of-the-line option for 1970 and 1971. Better still, it was available in coupe or convertible form. It cost around $900 over the price of the standard Barracuda. They installed it in just about 600 coupes and only 17 convertibles during the two-year production period. Brace yourself, because the prices for those 17 cars range from $2 to a staggering $4 million.
