Today my neighbour drove her car into my wall and knocked the end pillar off and half of the wall next to it. The main pillar luckily missed the back of my CLK, but part of the wall did catch the rear bumper and left a small 2 inch scratch. My neighbour's husband called round to say about getting it sorted and to give my insurance details. Ive never had to claim anything or give my details before, is this the correct procedure, will it affect my insurance?
