Price: $4.8 Million

Koenigsegg introduced it's "most-affordable" model, the Jesko, this year in Geneva. But the diamond-coated, $4.8-million CCXR Trevita sits on the opposite end of the Koenigsegg price spectrum. Finished in a proprietary Diamond Weave finish exterior (essentially carbon fiber covered in diamonds), the Koenigsegg is motivated by a twin-turbocharged 4.8-liter V8 with 1,004 horsepower and 797 pound-feet of torque. The company built just three examples before discontinuing the CCX for good.
