IF you want real advice, there really inst such thing asa perfect alarm... if theifts want to steal it they will, my friend trish had over $28,000 invested intoj her teg, she had this for security:
-2 way pager
-relcated battery
-back up battery for siren
- low jack
- 2 fuel cut off( one w/ pager)
- relocated hood release
and her teg was STILL STOLEN!! you can only prevent crimes from happening never fully stop them...best method though would have security cam on your car whereever you park at night and carry a 9MM gun next to you in bed lmao
