3: Cadillac Series 62 – 1957
The Cadillac Series 62 is one of the most iconic original Cadillac models on the road. When you think about a performance sedan, the Series 62 wasn’t it, but the car could hold its own on the road. The shark fin styling became iconic for big and bold American sedans and the 365 cu in (6.0 L) OHV V8 could handle its own. The reliability of the Series 62 was one of the strongest selling points for the car. There were four-door and two-door models and there was even a convertible version of the car as well.

Cadillac did a great job of selling Series 62 to the public and as such, there is a surplus of used models on the market. The Series 62 is not as well known as the Eldorado, which made the car rarer to find and customize. But the value is more affordable and you can build one of these cars pretty easily.
