I've bought two bikes on eBay, but made sure they were both close enough so I could go inspect the goods and title before handing over the money. In other words, pick up the bike personally if you don't know the seller. There are too many money transfer scams going on out there. As for the eBay bikes you're looking at, there always seem to be one or two scam listing out of the 20 or so that are posted at any given time. They are usually obvious and comical... tricked out busa with every mod possible for a "buy it now" price of $3,000. Usually the seller will have some story of how he is overseas and needs to unload it. Wire transfer the money, etc. etc. etc. If it sounds too good to be true, it is.
