I've got a brand new Crime Guard 745i3 Car Alarm for sale. I originally got it to put on my Talon, but I've got a rod knock and basically I have no need for it now. It's never been used or installed. The box has only been opened to look at the contents. Please take a look at the specs on Crutchfield's website for all the information about the car alarm.

Maybe you could learn to do it, but from my understanding it's a decently complicated install. You've gotta put sensors and stuff all around the car and do wiring etc. I know I wouldn't be able to do it, but perhaps you could.
