I'm going to make this short, because just talking about it pisses me off a little bit, mostly because I went against my own better judgement.

This guy called me as a potential buyer of my motorcycle.  Lucia and I went to the dealer, where they were selling my motorcycle, picked the bike up, and drove it to the guy's house that called.  He met us outside his apartment building.  I refused to let him test drive the bike without me driving.  We drove about a kilometer away.  We stopped, he asked questions about the bike.  He demonstrated to me that he knew how to drive a motorcycle, well enough to stay very close, so I let him.  He stayed close.  I finally jumped on the back with him and we drove in the same area together.  He really wanted to drive it by himself, a little faster, to feel the power with just one person.  I let him.  He drove slowly down the road, took a left turn, and I haven't seen him since.

I called Lucia, and she was happy to hear that I was alive, since the apartment number he gave didn't exist, and no one in the building knew anyone by the last name that he had given us.

Moral:  Don't be a trusting foreigner.
