for lojack the cheapest price i seen is $695 but most prices ranges up to $1k. if u paid 500 that is a hell of a deal especially coming from a dealership. also lojack if ur car is stolen and not found within 24 hours they dont pay u no 5k all they pay u is the price for the lojack and install. check the lojack website. so all the parts stolen or strip u have to go for insurance for that. with a gps system u can go online and track ur car down instead of depending on the cops and lojack with lojack there have been some stolen striped car with lojack so no alarm is a guarantee ur car will not be stolen or safe.
