I have a viper right now, I'm not sure what model it is but its pretty old because it came with my car, but I plan on getting a new viper alarm from my sisters fiance since he owns a audio/alarm shop so he's installing everything for free and I'm getting the alarm at wholesale

...almost every possible option on the alarm possible installed even a kill switch.....
if you plan to be hardcore... just take out your ECU everytime you get out of your car... now thats an alarm.....
