Feel really bad for you Scotty.
Wish you could have caught them and 'educated' them re their ways
As Donny says, probably one of many - when I had my Supra it was one of 11 cars in a row to gain a large smiley face scratched into the bonnet - by two 12 year olds - caught doing it by one of the other owners - police called - kids denied it and said car owner was lying - parents supported kids - police said they couldn't do anything....
Another example of too soft, touchy-feely, oh-the-poor-kids-must-have-had-a-hard-life, modern justice that doesn't dissuade scum from breeding scum!
Hope you get it sorted easily buddy (sorry for the rant - makes my blood boil!)
