One thing I haven't seen yet is a really high mileage Model S hit the resale market - have you? Curious to know what a 100K, 3 year old Model S would go for - it's out of bumper-to-bumper warranty but still within the 8 year unlimited mileage battery/motor warranty. Surely many people with huge commutes bought these back in 2012/2013, but I don't see them for sale. Hypothetically what if some traveling regional sales manager type put 50K per year on their Model S and now want to unload it for one with autopilot - say it has 150K miles on it but it's only 3 years old. This oddball must have a weird depreciation curve - the worn out parts would be suspension related (shocks, bushings, ball joints etc.) and easily replaceable. Battery and motor would still have 5 years of warranty left. What would it be worth? I wonder if the market will set some kind of floor for extremely high mileage Teslas still under the battery/motor warranty. On the other hand, increasing levels of autonomy will keep making older Model S's less desirable, so that effect would push in the opposite direction. Anybody have a data point?
