Don't worry, I went through the same circus trying to buy a 70 Polara Custom HT from a guy out of Michigan. If trying to get hold of him wasn't bad enough, he too was deeply suspicious of "foreign" (I'm from Australia) buyers and after a couple of weeks of negotiation and arranging a means of paying cash, at the point of a virtual agreement someone else walked up and handed over cash for it (it was one of those dream finds IMO, so it had to happen). Bummer. However, the blessing in disguise was a more keen and trusting guy from Florida was happy to deal with me and I ended up with my first choice - a 70 300 HT.
