American muscle meets European styling in this obscure California-built sports car. The Anteros is built on the bones of a C6 Corvette, but features a full carbon fiber body with unique styling, a full leather interior, and a range of performance options. With a biturbocharged LS3 engine, the Anteros will produce up to 600 horsepower (447 kilowatts). The coachbuilt coupe has been around since 2009, and costs $149,500.
