best thing to do is get a pager alarm system comes with immboizlier not from factory but better, and tells u if someone has triggered ur alarm. get the club, depends where u go to, park in public places. and if that still isn't enough get the GPS system. u are going to pay a monthly fee but if ur car is a nice car u going to need it. my friend has it in his supra TT. basically u can track ur car down anytime anywhere , and even shut ur car off if ur not driving it.
