06gt1858, I wouldn't entirely discount the foreign buyer. Yes, some are just talk, but there are many rich people living in Dubai. And most anyone that attempts to purchase a hard to find car knows that we are smart enough to protect ourselves from any scams.
You may be able to get a premium price, and yes, it may be slightly more complicated, but there are some very wealthy individuals from than part of the world that could buy your Shelby and the dollars envolved would mean absolutely nothing to them.
I've sold two cars over the years to overseas purchasers without a hitch.
Just a thought, but be careful.
