This might just be the most brilliant thing you can do to keep your car from getting stolen.  A guy in Chicago bought a car boot on eBay, and puts it on HIS OWN CAR every time he parks . . . just to keep people from stealing it. 

He got the boot for $100 off eBay, and what he's doing is totally legal . . . there's no ordinance against putting a boot on your own car.
