We're close to 90K with our late 2012 S P85.
It's in great condition - interior is excellent - and the outside has a few parking lot dings, but considering it's almost 5 years old and has seen a lot of miles, other than losing a little bit of range and not having all of the features added on the later models, the car is still fantastic.
We had a charging issue in late August. We had a power surge when Hurricane Harvey came through Houston, which may have damaged the charger - and when we evacuated to Austin, Tesla replaced the charger before we drove back to Houston.
We had a front trunk latch problem during a 2016 road trip, which popped the frunk lid - and it wouldn't latch, so we were unable to drive safely at highway speeds and required a tow to the nearest service center. Since we had the extended warranty, Tesla replaced everything related to the frunk latch - and it cost us only the $200 deductible.
We also had some bubbles on the touchscreen display - Tesla replaced the display. Evidently there were some quality control issues with some of the early production cars, causing the touchscreen membrane to separate.
But, compared to an ICE with almost 90K miles - we've really had few problems...
