The scams are getting very elaborate. My son-in-law was looking at a "too good deal" on a ski boat and asked my opinion (me being "wiser" AKA more suspicious in nature). The scam included a legitimate looking (real) shipping/escrow company, but when I Google Earth'd the shipper the site looked run down and then BBB searches brought up other issues. I called the shipper and said I will come by in person that weekend with cash to pick it up, which resulted in a hang up and quickly disconnected number...
Reported it to BBB, but I'm sure it will pop up again under a new name.
