If you're worried, buy an Autolock X and use it when it's parked in a higher theft area. You can get it off their web site (Unbreakable Autolock) or they sell them at Autobarn. They really are tough to drill/cut off, and with it locked around the brake pedal I don't think the transmission can be shifted out of park even using the lock-out override tool. When not in use it can fit in the space behind the passenger seat.
