The safe and sound service which is door lockout, flat tire, out of gas, remote diagnostics, air bag deployment, emergency services and gps locating is only 16 bucks per month. I upgraded my package and went with directions and connections + safe and sound and love it to death, will not have another GM without onstar.

Another way to go is outside of a car alarm with hood pins and starter disable is as follows, when I bought my silverado it came installed from the dealer with a starter disable. The company that makes the disabler guarentees that if your vehicle is stolen and not found within I think 30 days they will buy you a new vehicle. Now there is probably some fine print that gets them out of it, but it worked really well if you didnt mind another key fob on you keys.

is the starter disable an aftermarket item???
