As a dealer I do not as part of my policy trade in or sell cars with Cat C or D attached however recent or distant it happened. That is my choice, my business.
But the proof of the pudding in what you are stating comes down to this :-
Would you knowingly buy a car with just such a history over a similar spec/history car without the "tainted past" if both were priced the same ?
I believe no one would. The cars are put on the register for a reason, that being that at retail price, using manufacturers geniune parts it was uneconomic to repair. However if a private person buys the car, effects said repair in their own time, not accounting for cost of said time, they will be able to salvage said car. But will it repaired to a good enough standard ? were genuine new parts used, or non std or second hand, was it jig aligned or merely pulled out using a "dozer" and a handy RSJ beam ?????
Stolen & recovered usually suffer less on the surface but sometimes they were more than just S&R, accident damaged or all of the trim stolen or whatever. It just seems easier to buy a straight one or buy the one concerned but at a reduced sum
