hell hath no fury

Another reason I don't want a new car.

The Texas Auto Center dealership in Austin installs GPS devices that can prevent cars from starting. The system is used to repossess cars when buyers are overdue on payments, said Jeremy Norton, a controller at the dealership where Ramos-Lopez worked. Car horns can be activated when repo agents go to collect vehicles and believe the owners are hiding them.

This was most likely one of those Buy Here, Pay, Here places that sell used cars to people with no credit. I know they use systems like this to make sure that people actually make their payments. So if you buy you're car from a reputable dealership or a private sale you shouldn't have to worry.
