It's kind of odd that you say something happens to you every November. Do you think it could have been someone you know? A lot of times its someone that knows you park there and what you have in there that does the damage.
One time some hooligans came and broke one window in each car on my block. We had all five of our cars parked out front that day. It was in the middle of the night. It wasn't pretty either. Nothing was stolen though, just broken windows.
