You know its really simple to put a fuel cutoff switch in there.. All you need to do it put a switch off the fuel pump relay and hide it somewhere you wouldnt think to look like under the ashtray or something ( Not where mine is, but a good idea ) ... Throw it every time you get out of the car.. If someone trys to drive off with it , they might get to the end of your driveway. I have one on my Z and it actually came in handy in TX. I came home one night to find my car at the end of my driveway with the door open, window broke, and the steering collar broken. Oh well at least I still had the car.
