This happened to us this evening and I was shocked by their response. We asked for their details - insurer, address, etc. and they (well the man as his wife/partner disappeared and it was her that did the damage) but he claimed not to know them. He said we were making a fuss about nothing - a couple of inches and several layers of paintwork is not nothing in my opinion. He proceeded to tell us that there were other marks on our car (one on our boot done by garage when in for a service) and that we should have been more concerned about our children who must have needed their tea. They were actually sitting quite patiently waiting for us. He even went so far as to ask DH what his qualifications were as he gave his title as Dr (as it appears on our documents). Feel really annoyed - what would you do? Would you pursue it or let it lie?
