Callaway is a company in the US and in Germany that turns brand new Corvettes into supercars by adding superchargers, massive brakes, their own body kits, wheels, custom interior and colour schemes. Basically you give them your brand new Corvette and an extra $75,000 US dollars in return you may end up with one of the most outrageous Corvette with up to 5 years and 100,000 miles warranty.
