I bought (or almost bought)a 67 C20 that was advertised to have 28k and a 1 owner truck. When I got there with the cashiers check, the story changed. The odometer had rolled over at least once if not twice, no documentation, and no knowledge of original owner or family. Needless to say, I backed out of the deal. That was my only bad experience with Ebay out of about 30. Otherwise, it has been a terrific resource.
