not impressed today...

we were having a skip delivered at work and had to move my car onto the road out of the way, the drive is very tight and the road pretty narrow.........the skip wagon driver was blocking the road and my bro parked his van realy tight near mine....anyway this stupid old git tried to squeze through the gap between the van and my car and scuffed my work motor............he was stopped and tried to blame my parking........he came off worse i think and said he will pay cash for the repair........got all his details and pic's of both car's....so how much do you think it will cost to repair these scuff marks that will be removed by myself i was thinking of around £100.00 from a scratch place
