I would look at a Cat D, but I would have to know what the extent the damage was and that it was not repaired by a Yee-Haaa. You can certainly save a few bucks. As for a high mile car, as long as its been maintained correctly, then thats not an issue for me either.
Also I think the stigma of a Cat D type thing is certainly a UK thing, or a lot worse in the UK . . . people could not really give a toss here, even though you have to state if its a crash/repair if you sell a car, servicing seems to be far more important, there is no such thing as an MOT here so poorly maintained vehicles are everywhere.
