an immobiliser would be a good start, maybe a pit bull in the car overnight, the rotor button is a good idea, (who carries one of them around while hunting for a car to steal) put a sticker on the steering wheel mentioning that you don't want to do another life sentence but if you have to you will. or sit in the dark with a baseball bat and see if they come back and if so hit them, it's a very good deterrent.


i was working on the verge of my old house under my old 180B and had some guys come past and yell some abuse so i stuck my head up they stopped and got out "young tough guys all 5 of them" i picked up my 4x4 temp wood crossmember put it over my shoulder as i stood up 6'5" and they all ran back in the car. big lumps of wood are good deterrents.....

but the steel loop in the floor is a good idea i'm going to have a couple of those in my shed for my motorbikes...
