We just sold out S and we have an X on order. My biggest concern with the S considering we had right at 30,000 miles in a year was the fact, the warranty goes away after 100,000 miles to include the extended warranty. i'm feeling I may not want to drive the X as much as we did the S but then, why did we purchase a Tesla? So, this hangs over my head that after 100,000 miles, I'm left to doing the same thing. I'm thinking by then there will be more demand for a 3rd party Tesla repair centers, more and more solutions on line and easier access to Tesla tools.
