hopefully you could get a better parking area to be safe and make your car safe as well. i know how difficult having no car at all, rent? well another part of the budget.... but anyhow that's the only thing you could do. It is so disturbing at work also, you go to insurance, to industrial for how many days depends on how damage it cost and likewise. So hopefully next time try to put your beloved car in a safe place called "parking area".
