Ferrari Enzo — $653,000

Named after the Prancing Horse's legendary founder, the Ferrari Enzo was built from 2002 to 2004 using Formula One technology. All 349 of the Enzos made were sold before production even began — to customers who already owned Ferraris. Fifty-one more were built later; one of which made an appearance in the movie "Charlie's Angels: Full Throttle" (actress Demi Moore was behind the wheel). The interior of the Enzo almost looks half-finished, with leather upholstery covering only the front of the carbon-fiber seats and rubber mats resting on the bare carbon-fiber floor. The effect is as if you're peering into an engineering lab. Because it's no longer in production, the Enzo reportedly fetches around $1 million at auction or when sold privately.
