While driving slowly along a narrow road, a car that was parked on the side reversed into my front door. This was three months ago. I noticed him reversing and sounded my horn but he continued to reverse. He admitted his mistake and we exchanged names, phone numbers and addresses. He said I should get the damage repaired privately because he did not want to pay the excess and his insurance premium will rise at renewal. The next day I got a written quotation from a Mercedes franchised body repairer of £750. The other party suggested that we should get a second quote from a body repairer he knows. So we met with this body panel person who said he could fix my car for £200 cash. I wanted my car to be repaired by a reputable garage and so reported the matter to Admiral (my insurer). Admiral has told me that the other party is denying having an accident on that day. I would appreciate your advice as to how should I proceed now.
