I'm skeptic about the common notion of "If someone really wants it they will get it" mentality. Really, does someone "REALLY want" YOUR car that much? I mean unless you have mayor $$ in stuff on the car, and unless you left it in very easy to aproach areas, theives will basically see your car as an item of opportunity. If it's easy, low risk and good reward, they will try to break in. If not, they will move on to the next car. I think the balance is not tilted all the way towards thieves. Also, I think theft by use of towing is less common than people like to think. That's probably done in high priced vehicles that are really hard to steal. IMO
