Just what the topic is. I have an 88 7mgte and it WILL be a target at my school. Its unfortunate people have to be so immature and damage cars when thy're drunk. I want to be prepared. I'm looking for something that will respond to things like tapping on glass, breaking glass, movement of the car from someone hitting it etc. Keyless entry is mostly a given in this. Anyone have any suggestions, also with your suggestions please give info on price and price of installation if you know. Also, any plug'nplay ones out there? (not TDSE since i will never find that) Thanks.
