An interesting thing I discovered on eBay Spain is that they have a section set up for local sales, cash, apparently designed for local pickup. Kind of like Craig's List (if you don't have that, it's like online web-based classified ads, but free), but run by eBay. No protection for buyer or seller except caveat emptor. I found a Laverda part I wanted but it turned out he wanted WAY too much for it.
But it raises a point, here's a seller in Spain, no contact info except a mobile phone number, selling parts of totally unknown provenance, no feedback check possible, no PayPal. I don't have any reason to suspect that this seller is anything more than a bit naive about the value of his parts, but this would be a way a stolen Laverda could be disposed of as parts without eBay safeguards triggering an alarm.
