Saleen S7 Twin Turbo

Saleen may be shrouded in mystery and controversy, but there's no denying the brutal performance of its S7 Twin Turbo supercar.

The S7's 7.0-liter V8 put 750 horsepower to the rear wheels, launching the car to 60 mph in just 2.8 seconds, and a (claimed) top speed of 248 mph. Best of all? You can apparently still buy one new.
