LoJack works but it depends. If you live in an area where crime is high it might be worth it.
Remember that VWs have immobilizers. The car cannot be hot wired. The only way to steal it is to either defeat the immobilizer *requires special equipment which most theives don't have, or put it on a flatbed truck.
IMHO, you're much more likely to have somebody smash the window and steal the radio than have them steal the car.
