thought some more about it after i logged off! I know you have last owners details , i would make the call , nothing to lose - especially when you put it top them your not after anything but help "one audi nut to another" .
when you sell a car to a trader IIRC they fill in the red slip so that for the time it is in the traders possession it does not acrue another owner on the log book. it is possible 'daves body shop' had it on the red slip before selling it onto carcraft/third party whom then had it in their name on the red slip. However , to do this the V5 would have had to go back to Swansea for a new V5/red slip to be issued.
I know you can pay £5 for the list of previous owners/keepers , i dont know if 'traders' whom never had the V5 in their name (just the red slip) would show up on the print out from DVLA though.
worth a punt !? might just prove carcraft knew exactly what was going on.
even if the V5 check comes to nothing the previous keeper might give you a name of a body shop/third party it was sold onto.Someone/somewhere will probably (hopefully) have the proof that it was sold to Carcraft with them in full knowledge of its previous history. :eyebrows:
