Be very careful! I nearly got done the other day when I was looking for an outboard, I was called in response to a wanted ad for an outboard, the guy was well spoken and we spoke several times on the phone,
I was emailed pictures and arranged a time to collect it and then he had an idea of shipping it to me through his dad's engineering business as it was only £56.
I got suspicious so I Googled the type of engine and sure enough after looking at two pages of images there was the engine for sale in the USA in a dealership.
He offered me his address, scan of his passport and his home phone number
He even had a kid crying in the background. Thinking back he only got very minor details wrong and he was very good at what he does.
So don't buy anything unless you collect it and see it working and DO NOT transfer any money to anyone
His name was Ben Owen......
