1971 Plymouth Hemi ‘Cuda Convertible
Even though hemispherical combustion chambers have been in use since the early 1900s, Chrysler had been the one to make the Hemi engine so popular. The automaker also gave it the affectionate nickname! From 1970 to 1971, it was the top-of-the-line offering from the lineup. It was definitely expensive for an average Joe since it cost $900 more than the base model. The convertible option had been even more elusive. It was in production for two years, but only 17 units came with the Hemi and the convertible feature. Originally priced $4,348, this car is now worth $2,000,000 to $3,500,000.

1967 Shelby GT500 Super Snake
A 1967 GT 500 Super Snake hand-built by Carroll Shelby himself went for $2.2 million in an auction held in January 2019. The value went up by $900,000 in only six years, so it is the most expensive Mustang in history. This is a shoo-in for the title of the best American muscle car on the planet! Shelby built it in a partnership with Goodyear, who wanted to try out the “Thunderbolt” tires. It was made with the goal of crafting a high-performance race car that could outdo the competition when it comes to speed and still retain its tires. To try it out, Shelby drove it at an average speed of 142 mph for 500 miles. It is shocking to hear that the car still managed to retain 97% of its tread. Whoa. This car was never sold to the general public.
