Well, I drive american cars here which is the wrong side of the road to them. I also drive my work van in europe which is the wrong side of the road for it - trust me, you get used to it very quickly and it's not a problem. As for the winter - don't take it out - simple. If you took it with you, you would find the yanks have loads of stuff very well priced for doing resto work and it would be something you could restore and nurture whilst you are over there. For a few grand to transport it, it may be actually cheaper to take it with you, did you consider that?
Besides, you can take it to car shows there and you'll meet some great people and make new friends very quickly.
