Had the rear bumper damaged by an old fart who didn't even realise he hit the car. Luckily my son was sat in the car at the time and was kind of suspicious as the other driver was very evasive about his details, the police were called. Turns out his car didn't have an MOT. Anyway, got all his details and more importantly, a police reference number. Went to the local Lexus dealers and got an estimate for the damaged paintwork, £657, realistically there is a chance that it may polish out or a smart repair may do the biz, but Lexus are removing repainting and refitting the bumper. You can just see the feint scuff below the reversing sensor. Contacted the Op's insurance and they have checked out the damage and agreed to pay for the repairs, no quibbling or arguing, in fact the assesors view was that the car was undamaged before the accident so I'm entitled to have it put back as new, can't complain at that. Now the next thing is, do I report this to my ow insurance ??, or do I not bother as the case is basically closed...
