VIPER 800 ES. Engine Kill, Randomized Coding, adjustable sensitivity, page you, etc. Could you ask for anything more (other than lo-jack). but no matter what, if someone really wants your car...they'll find a way to get it. alarms won't do it alone. You'll need to get Auto-loc, and the club (ok, the club does jack but slow them down, but hey, precious seconds man!)
