Getting tired of the staid supercars sitting in your garage? Now is your chance to own the Guinness-verified world's fastest car, the SSC Ultimate Aero which was clocked at an average two-way speed of 255.83 mph - besting both the Bugatti Veyron and Koenigsegg CCX. Motorcars of Las Vegas, the sole distributor of the Ultimate Aero, has chassis #SSC-07-004 on its showroom floor ready for its first owner. This is the first one they have had for immediate delivery, and there are only 15 miles on the odometer. The twin-turbo V8 mounted amidships puts out 1183 horsepower and 1094 lb-ft torque. Other features include a full carbon fiber body, navigation system, back-up camera, and a front lift system to clear speed bumps. If this particular one doesn't suit your taste, you can also commission one to your own specifications.
