Really sorry to hear of your misfortune Alan.
There is only one course of action open to people that disrespect other peoples property, but unfortunately the law prohibits that kind of justice. Instead, we have to truely hope that the adage "what goes around, comes around" applies in the instance more so than ever.
The damaged area is probably not an easy repair, but an experienced restorer may be able to get them back to how they should be. As for the centre caps, you may be lucky enough to find some on ebay; otherwise it is probably a trip to the dealer.
Good luck at any rate.
