Your local dog charity might give you some advice. They might even (for a deposit) lend you a chip detector, so you can at least check he is really chipped.
If so you might want to check who comes up as the last registered owner - it should be the people offering him for sale. If not, check with the people named, always a possibility he was stolen.
Thought this might amuse some of you!
