I had heard of this type of thing happening before, but I thought it would be pretty rare. I would definitely have been suspicious if someone dropped him off. I have a feeling that will never see your VX again. Your best bet is going to be trying to set a trap for this thug. Where did he learn about your auto for sale? Post another rare vehicle and see if you can get him to come and "test drive" that one. Even if you can catch him, you are still likely to not get your car back. You are pretty much screwed!!! Have you called your insurance yet? Will they cover it?
