Three of my mates have Auto Watch security on their cars (2 Soarers, 1 Skyline), they've got auto-window roll up on arming, immobiliser (3-pt? I can't remember), back-up battery etc etc... I remember the prices $500 mates rates and $700 in the Skyline. I was planning on getting a Viper system fitted but I haven't been able to find a store that sells them. I've also heard that Flashpoint is also pretty good... black wiring, back-up siren etc... $650 installed
