the biggest market for stolen cars would have to be civics an crx's. I install many alarms on crx or honda in general. To be honest, an alarm is good to have, but can be overcome if the stealer knows what hes doing and how well the installer hid the main unit. To make sure no 1 steals ur car, i would haev to say the lojack is the best way to go. You cant make ur car 100% non stealable, u can prevent but not 100%. For those that own civcs or crxs go buy a few PIEZO (pain killing) sirens and place them inside the car. If they enter ur car that sirenwill literally make u go deaf, no 1 can stand that ammount of noise inside a sealed area. Good thing is if they cut the power, the siren has a back up battery active up to 30 minutes.
