I've always thought that using the "club" or other devices were sort of lame because thieves will steal anything if they really want it. one of my coworkers just got his car jacked though, in fullerton california (orange county!) and so it has me rethinking these "deterrant" devices. what is the best "deterrant" device for preventing auto theft? I park outside and have a pretty nice car that already has an alarm wired in it. One of my close friends uses one of those devices that you stick between the brake and the steering wheel. what do you guys think?
