In many cases, car theft would have been avoided if the proper precautions had been taken. Don't think you can be careless about your car just because it is old or not running properly. Car thieves often make more money by dismantling a car and selling the parts than by trying to sell it in one piece. An unlocked car is an open invitation to a car thief. Lock up whenever you leave your car, and take the keys with you.
Professional thieves have tools that help unlock cars through a minimum of open space.
Lock all valuables in your trunk or take them with you. While driving, watch out at intersections and stop lights. These are favorite spots for troublemakers. Keep your car in gear. If you are threatened, blow the horn and drive away.
