Do what i did. even though i have a slow diesel(which is not a good car to make a mad dash in) i have a kill switch in series with the starter realy. you can hide the switch in all kinds of places inside the passenger cabin or even in the trunk if you are going to use it ocassionally(bad idea if someone is chasing you to the car). with this installed it is had to find the wiring to jump it. it will not help if they just want your goodies, but to save your car that is a really cheap and effective way to go.
sorry to hear about all the damage..
