I'm looking into a car alarm system for my stang after the resto project is done. The car is not a daily and is stored in my garage which is alarmed by ADT & I'm mostly with the car when I'm out but there are times when it's out of my sight.I'm also thinking that maybe an agreed value insurance policy might want one or give a discount on it. I was looking at a Viper system with the added tilt & glass breakage sensors. Do they make a good system? also what other brands, types to you guys use?
