Suggest ask him politely and if he is a good neighbour, he will pay. I do not think going to the insurance company will get you much. This is because all car insurance carry a deduction when a claim is lodged. The amount varies from company to company. At the minimum they will deduct QR 300 but usually it is around QR 500. You will be left with hardly much in hand after going through all that hassle of getting a police report and then lodging a claim with the insurers.
