That's find but from a resale point of view it is always harder to sell. It is hard enough selling a car like with s limited audience but being a CAT D makes that even more limited. If it's a good but then why hasn't it been snapped up at mid 30's?
If the bumper is wonky the repair is questionable, I'd consider a CAT car if it was a keeper, repaired properly and the price was right.
If you want a particular car such as a GT and your budget won't run to a straight car a properly repaired cat car could be your only route.
For the same money I'd sooner have a cat car at 25,000 miles than a non cat car at 80,000 miles if I could see pictures of the damage and proof it was repaired at an approved body shop using new parts.
We could all be driving round in an accident damaged car without knowing because the insurance decided to repair it because the numbers added up
20-30 years ago it was either fixed or that bad it was scrapped, there wasn't any of this graded write off
I bought a car from a car auction last week , a fiesta went through, declared a CAT D because both doors on the passenger side were dented, a simple fix, buy 2 doors in the same colour a few bolts and it'd look as good as before the minor crash which wrote it off.
