Just got my S2k last weekend. Car is basically stock w/ floormats & windscreen. Looking to add an alarm w/ a proximity sensor. My choices in town seem to be Code, Viper, and Alpine. Visited all the shops and the one with Code seemed the most knowledgeable. I've done a search and see some folks recommend the Alpine SEC-8063 and the Viper ESP line but haven't seen anything on Code. Anybody used their systems with a proximity sensor?
