A new California-based startup, FlightCar, is offering free airport parking. Plus when you get back from your holiday, your car will be spotless and you'll get a $10 gas card.
The only catch? While you were sipping margaritas on a beach, a stranger was driving your fire red 1971 Cadillac Eldorado convertible.
Yep. I'm not making this up. FlightCar gets you to hand your car keys to a stranger, who hands them to another stranger who then drives your "sweet ride" away.

On the lookout for huge bats in Fear and Loathing in Las Vegas
to find a sweet vehicle you'd like to re, who then drives your car away. Every rental is insured up to a million bucks, and FlightCar does background checks on every driver.
Basically it's a matchmaker service for someone flying out of an airport who doesn't want to pay $30/day for parking, and someone flying into the same airport who's too lazy to steal a car.
Benefits for the car owner:
Free airport parking, free carwash, free valet, fully insured, and your vehicle is covered for mechanical damage caused by misuse and gonzo driving. Plus you get the satisfaction of knowing that your special bum cheek dents in the driver seat will stay filled while you're away.
