I personally have not. However, as friend at work collects classic cars and ships all the time. He has NEVER had any difficulties that I was aware of. I know he uses several carriers, but mainly uses and firm called Horseless Carriages here in the east. I am not sure if they are nation wide. I will try to find out more info if I see him. Our office hours vary so I do not frequently see him, but I will try to find out.
