The way I figure it, if a criminal is intent on doing something, they are going to find a way to do it, but you can do things to make it more difficult. Obviously the most important thing with a car like these is full coverage insurance, but as far a prevention, I have "several" battery/ignition kill switches, as well as a cable with a built in lock that I initially ran through the wheel to the frame (crawling on the ground got old real quick), but am now looping through the door hinges and the steering wheel. I like the new set up (sorry, no picture) because it is a visual deterrent, the drivers door will not open, and I always turn the wheel all the way so the car will turn if towed. I force myself to do all of this whether I am parked at home or at the store, just to make it force of habit. Beyond that, I do worry, but I do know I am covered if something should happen.
Of course the first day I picked the car up and was in a hotel I had to improvise.
