As much as i'd love it, I can't see it happening. You're not going to get them over here in he middle of the season, so that rules out Feb - Nov. They're not going to come in January cos they're too busy testing. That leaves December, and I can't see Nascar being enthusiastic about coming all the way over to Europe in December whe the likelihood of races being washed out/iced out/snowed out would be very high.
