This is an old scam and it isn't linked to just vette's. I had a Harley for sale about 3 or 4 years ago and got a call from a guy in Canada. He said he worked for a broker and needed the bike shipped to Germany for a show. He said he would pay my price plus send extra ($9,000!) to cover shipping. Catch was had to be shipped immediately to get there by show time. Scam was by the time the check bounced, the bike would have been in Germany and I would have lost cost of shipping. I even talked to this guy on the telephone. I could not find any info on his brokerage, so I did not bite! The clue was that he did not even quibble about the price!
