Had a viper alarm fitted. Immobilised, microwave-sensor, shock and glass. Cost $900 including install. Would cost more to include remote start, window or boot operation but I dont need that shit.
You can d/l an iPhone app that tracks your car, locks, unlocks and can start it but you have to pay subscription, didn't bother with that either, bit of a gimmick. Plus, if I lose my phone I don't want some prick starting or tracking my car.
