I'm trying to decide between Viper 5104 and VSM250 with their GPS Secure plan. With hardware and 3yr service my cost is about $800 for 3yrs. compared to OnStar Safe and Sound service (already have installed hw) which would cost about $500 for 3yrs. The 1 thing the Viper doesn't do that I would consider very important that OnStar does is give you vehicle stats as well as monthly vehicle status and code readings.
What say you??
