a car is categorised C or B by the insurance as long as a VIC (vehicle identity check) is carried out at a vosa test centre ( they carry out a vehicle inspection and check the vehicle over for repair and legality) then they will forward their report to DVLA and they will then issue a logbook for that vehicle, totally legal and correct. My policy does cover me for all cars but I do have to list them individually to be covered correctly. An engineers report is an in depth inspection and shows that a vehicle has been repaired back to a high standard, this is then enough for an insurance company to be confident that the vehicle is fit for purpose and insurance
