What is Category C and D Vehicles?

Categories C and D were the pre-2017 insurance write-off markers. Category C meant repair costs exceeded the vehicle value but repair was possible; Category D meant repair was uneconomic though damage was lighter. They were replaced by Categories S and N, which focus on the nature of the damage rather than cost alone. Older vehicles still carry C/D markers on history checks, and these classifications remain relevant when buying used cars first written off before October 2017.
