Sadly I think any car seems to be a target now - this is my first car that has been vandalised (though I wouldn't have noticed on my previous one because it was so dented, dinged and scratched), but at uni every year for the last four years something has happened to one of my housemates car (Seat Arosa, Renault Clio and another Mini), just jealous people, probably drunk half the time round where we live. I wouldn't be overly worried.
