That's funny that you called the bank, as I did too! Some history on me: I'm a retired police detective/fraud investigator. Even though I knew full well that having the guy wire me the money was a one-way transaction, I called the bank anyway just to be sure I wasn't missing something. The bank confirmed, saying, "He can't rip you off, but you certainly could rip him off!"
The guy that bought my plane was a really nice guy, but I can't imagine ever buying something like a plane sight-unseen. Even when he arrived to take possession, he looked at the plane from one spot for like 10 seconds, said, "Yep, looks great, just like you described." Then he took the keys!
