Twice in the past 12 months, my wife's leased Mercedes has been bumped whilst stationary or parked and on both occasions, the lady drivers concerned admitted responsibility immediately. Because the car was owned by Mercedes, on both occasions I insisted upon using the local Mercedes garage for repairs. I did not involve our own insurers on either occasion, but simply wrote a formal letter to the ladies concerned attaching the repair estimate (£500 for one and £1,200 for the next) and asked them to forward both to their insurers without delay. The Co-operative and Zurich insurance companies both responded promptly and both offered to get third parties involved on loan cars and "accident management" but when I explained that all I wanted them to do was agree to the repair and pay my choice of garage direct with no loan cars or anything else required, both did just that. When I renew my insurance in two weeks' time, should I declare these successful claims against third parties despite the fact my own insurer was not involved?
