There is no such thing as an anti theft device.
You can purchase "slightly more difficult to steal quickly" units though.
If someone wants it bad enough they'll get it.
Make it hard on them and they'll usually wreck it and move on. Been there.
haha when i was a kid we would go to the store, dad would leave the keys in the car, doors unlocked, windows down if weather permitted, he figured if they want it they can have it, if he locked it they would just break in, then if it was recovered he would have to fix it! i miss those days!
