From a trader's point of view certainly a bargaining point at P/X but when put on the forecourt for sale all of a sudden Cat-D is 'a minor accident that doesn't even appear on the V5'

Very true. I remember I bought a 3 year old Citroen BX TD estate and was tempted to px for the Xantia when it came out. The salesman who sold me the car 6 month earlier went around the car and pointed out some minor defects. I told him that was very strange as he'd not pointed them out when I'd bought the car from him earlier. Result was I walked away and kept the BX for 11 years
