If you ever saw the show Repo Man: Stealing for a Living, you know that taking back a car from a deadbeat buyer can be a challenging -- and expensive -- ordeal.
Now finance companies who work with subprime car buyers are fighting back. The Sekurus Company offers lenders a "payment protection system." If you're behind on your payment, a small device installed in the car beeps. Make the payment and you enter a pin # and it stops beeping. If you don't pay, Sekurus' device will turn off the car's engine!
