CAT D Vehicle rules/paperwork?

[ginge191]

Browsing vehicles and Category D cars are coming up all over the place

Most can be rightly wary, but CAT D only refers to cosmetic damage outweighing the value of the car.

I've just phoned a dealer on a car i'm looking at and asking what paperwork comes with the car's CAT D status and he says paperwork from the RAC and similar are optional.

Is there any paperwork that MUST be presented. They're a warehouse dealership who have a fair few decent cars and a fairly reputable name. 

Tinternet states that CAT C or B vehicles need a VIC pass marker, but CAT D? not a lot of information

If a vehicle is damaged and an insurance claim is processed for it, the insurer will either authorise repairs to the vehicle, or write it off (declare it a total loss). If it is written off, it will be recorded in a write off category, A, B, C, or D. A and B cars are so badly damaged they should never appear back on the road. C and D vehicles can be repaired and returned to the road, but you should exercise caution with them, and check the repairs have been done correctly and fully. A vehicle inspection should be able to confirm the quality of repairs and general road worthiness of the vehicle. If you buy a category C (or B, if you're looking to break it for parts), make sure that it has a VIC pass markeragainst it otherwise you won't be able to get a new V5C registration document issued for it.

If anyone can give me a heads up on this, would appreciate it
