6: Mercury Marauder X-100
Mercury is a brand that was often overrated. But there were quite a few iconic cars that came out of the brand. The Marauder was a muscle car with a lot of attitudes. Mercury marketed the car as a police package and a standard consumer package. The 429 CID V8 engine gave the car a good deal of performance to work with.

You don’t see very many of these around, but its power rivaled anything that you could get on the market. The Mercury Marauder X-100 is among one of the most underrated performance vehicles on the market. The resale value of the car is reasonable enough that you can build it up easily.
