With world wide production just starting, I don't think there is a problem with Model X demand. I think they are running through the current US backlog, but problems aside, the reviews are excellent and I believe US demand will only grow. The only problem I see right now is with production and quality control because of door latch problems and other issues. I hope they have found solutions to the problems and are applying fixes as we speak. I hope that is the reason deliveries seem to have slowed down with long factory QC times this month. I will post when we finally get our car, and if I learn anything else about current and future delays.
