I have seen some people say since Tesla has so few moving parts, they expect to get 3-400,000 miles out of their Tesla. I'm thinking 200,000 is more realistic before it starts to get too expensive to justify the work required to keep it, but I have zero basis for that. How realistic is that? And would the cost be worthwhile at that point? I know they have only been out a little over 4 years, but what is the most miles anyone has heard of on a Tesla?
