I had this problem as well although the car I bought was imported from Singapore. A bit annoying as the Chassis Number, Parts etc. are all the same as any European car. Obviously just slapping my wrist for buying outside their cartelI know the audi main deal in mayo wont service or take trade in of imported cars.
Can't see how this makes sense. If they find a nightmare they will charge you for it.They recon that the risk is to high for them if they go to carry out a small job and it turns out to be a somebody else's nightmare.
Glad to see that many dealers are now accepting UK cars as legit now though
