1970 AMC AMX/3
This might not be the car that you think of when talking about American muscle cars, but it still counts. The American Motor Company created this model as a concept car. An Italian car maker called Giotto Bizzarrini designed the third generation of this car, which boasted many engine components from BMW. It received great reception during the Chicago Auto Show, so AMC wanted to produce thousands of it. However, the increase in manufacturing costs made it change its mind. This is why the company decided to abandon this project. The five prototypes are the only ones ever made. If you put up one of them on auction, we are sure that it is going to go up to seven figures in no time at all. Originally, it was worth $14,000.

1970 Chevrolet Chevelle SS 454 LS6
A classic, most people will recognize the Chevy Chevelle. However, American muscle car enthusiasts know that Chevelle collectors are drooling for one model in particular: the LS6. These units were first in production from 1963 to 1969. This model was considered to be an affordable yet powerful model with a nice engine and attractive design. In 1970, the automaker changed the game by introducing more engine options. The standard units already came with an impressive 454 big block V8 engine. Aside from that, it also got a larger carburetor, racing features, and more than 500 horsepower. Its original price had been in the $4,000 to $4,500 range, but it now goes for $1,200,000. Whoa.
