someone smashed my sisters civic window 2 years ago. When i got my teg i have the best coverage i can get, although its $230 per month!!!! Mine has a alarm also...key in ignition does nothing if alarm is not shut off...but im sure if someone knows what they are doing then no problem. Also since my car sits outside near my shed we are thinking of installing a small camera pointing on the cars with a moniter in my room so i can see at night.
