Shif_tea,
There may be some hope, we had a Xmas party at our place and about 9 cars got scratched, some only on one panel, others completely around car. Approx $30K to $40K damage. Turns out to be little 7 yr old girls not really knowing what they were doing. The parents actually were going to bank to borrow money to repair cars when by accident found that the parents House & Contents Insurance, under the Contents public liability covered the damage.
I know sounds weird, but the people have had their cars fixed. So if you know who the parents are, and could find out if they have Contents insurance, then there may be some hope. Perhaps ask the Police to chase that avenue for you.
Good Luck !!!
