I got an all singing and dancing alarm from a place in cumbernauld, had it fitted to my subaru, this thing cost me 350 but was really high tech, sensors for folk approaching your car, gave a warning noise, doors locked themselves when you go over 5mph, can't role the car away alarm would go off, bonnt and boot was all hooked up, can't mind the name of the place, google it, failing that buy a big dog and a big bat
