What a bummer. Years ago when I lived in the city someone messed with one of my cars. I installed a motion detector burglar alarm that had a pager.
The first time it went off there was a cat sitting on the car when I came out of the house.
The second time it went off the paper boy had hit it with the morning paper.
The third time it went off as I came out the front gate with my 12ga a car across the street took off burning rubber.
Nobody ever messed with my car again.
