Outrageously cool custom cars

This Swedish looker is the brainchild of 37-year-old Christian von Koenigsegg, a self-proclaimed inventor. With a carbon-fiber monocoque and carbon-fiber chassis, the extremely light (2,600 pounds) and rigid CCX certainly appears to be the stuff of dreams. Koenigsegg has gone to extra trouble to construct his own engine -- a twin supercharged 4.8-liter V-8 that makes 806 horsepower.

If that isn't enough -- or if you're environmentally sensitive -- Koenigsegg offers an E85-powered engine that makes 1,018 hp. Inside, everything you touch is either aluminum, leather, titanium, or carbon fiber. "When the car is open," says Koenigsegg, "it gives you an airy feeling unlike any other car -- it's more like a speedboat."

Price: $990,000 for the 806-hp version, $1,018,000 for the 1,018-hp E85 version
