Questions on items you want to bid on like serial numbers, VIN's or other identifying markings should be asked before you bid on eBay. This type of information is tracked by manufacturers and law enforcement to prevent theft/pawn. Unwillingness to share this type of information would scare me out of the bidding. I don't want to assist a crook selling hot goods. I would insist on being provided the serial numbers for a Yamaha outboard - those motors are stolen right and left and are often fenced with identifying markings missing or altered. Besides, if you buy it and have it serviced at a dealer, it may show up on the computer as stolen.
If they don't want you to know the serial numbers, want untraceable cash and won't even tell you what town they are located in, that would indicate something is rotten in Denmark. Caveat Emptor!
