Hi and thanks, yes I phoned him tonight - he is looking into it. I think he bought the car and sold it on. He said that he would contact the previous owner and check - I think he bought the car with the tax situation already in place.
My other gripe is with the DVLA though. Can they really just clamp you, get you to pay then even when you do pay up, keep you stranded with no explanation. If I hadn't phoned them to check, i would still be waiting in good faith following them saying they would release the vehicle...
