Well, it's 'cheap' but only if the body kit is made of carbon fiber and comes with chassis, rims and everything; sans the engine.
Speaking of which; I wonder what kind of engines this eccentric rich guy has put into these kit cars? 660cc engines from Jap dinkies or what?!
If I was him though (I wish!); I'd have put a 'Busa motor with a blower... Small compact engine with tons of power and decent mid-range torque, especially with a turbo. Ideal for these crazy "projects" with great exhaust note to boot.
