3. Shelby Cobra Super Snake – $5.5 million
Only two Super Snake Cobras were ever built. Both featured a highly tuned 427 V8 engine with a supercharger on top, providing the driver with almost insane levels of power and performance (via Road and Track).
In fact, too much power proved to be a deal-breaker for most customers because just a few people could handle such a car. One of two produced was recently sold for over $5 million.
