For $20,00 or less on eBay, you could pick up the Moller International M200x flying car. It's basically a "2-passenger Vertical Take-Off and Landing (VTOL) vehicle that has completed over 200 manned and unmanned flight demonstrations since 1989." Auction page.
Currently, bids are up to $18,888...but the reserve hasn't been met yet so you still have a chance to swoop in and snatch it up.[via Gizmodo - eBay]
