first off if it was one smash and grab it a wake up call but to hit the same car again and then break a few iteams it someone you know or kids in the area.look on local creglist and local pawn shops for your iteams.if any of your windows faces the car then set up a survalece cam to help catch the break ins.for car alarms you can also get a motion sensor add in for some so if the roll the windows down without breaking it and then get into the car it go off.also there are some car heads that can be removed fully and taken inside or pick up a head unit and logo if the head unit is stolen it never work again without the right key.
