4. Mercedes-Benz CLK GTR
The CLK GTR was produced from 1998-1999, though only 20 coupes and 6 roadsters were built. The production road car differed little from the racing car on which it was based. Interestingly, the car's V12 was actually increased in size as compared to the racing car. The 6.0 liter V12 was enlarged to 6.9 liters, providing 604 hp and 575 lb-ft of power. Those lucky son-of-a-guns who bought a CLK GTR had to shell out $1,547,620.
