Whilst certainly not to the same degree but my car was keyed in a car park recently.
I very rarely leave it out over night but a friend really wanted a go in it so I collected him, parked it in Waitrose and left it there until sunday morning.
By the time I came back it had been keyed, part of it back to the bare metal. The body shop can't really do anything as it will need the door and front wing matching to the tune of £320.00. So they are going to touch it in for me.
So that's now a car that when I look at it is tainted.
Like I said, certainly nothing to the description in the E90-92 forum. I would be absolutely gutted to come back and find my car looking like that. To know that it had been attacked by a random bunch of complete toss-bags makes you feel sick to the stomach.
