I don't know why you don't just call Shelby and buy a GT from him? I bought two sight unseen from him. They had no paint issues and were probably as clean as the day they shipped from the Ford dealer to the original owner - and I didn't pay him more than market for either car. They were both very fairly priced to me.
I look at the two of them every day and I have not a single complaint about either purchase. He did all of my work for me in that he checked out each one from top to bottom and saved me the trip down there. There are not many dealers out there who I would trust on a 200k+ purchase, where it's a sight unseen deal and money is sent before the car is picked up.
If I was buying a Veyron from him, I'd do the deal the same way I did the last two and not think about it. There are many on this board who have done exactly what I did through Shelby and I don't think you'll find anyone here who has anything negative to say about their dealings with him...and that goes a long way.
You really can't make a mistake buying through them. No one knows more about these cars than they do either. Take it for what it's worth.
