So the problem your facing is that it's an expensive car that is going (gone?) off warranty. It could be just fine, but it also could end up being expensive. Potential large expenditures are battery and drive units, less expensive (but not trivial) are things like displays, suspension etc. This isn't all that much different from buying any other used expensive cars, repairs can be a significant cost. What is somewhat different is that there a fewer non-dealer shops working on these cars so lesser cost repair options are less common if not non-existent. If you can afford a future $15K repair cost, then you'll likely love the car and hopefully you wouldn't have to cough large $ in the near future.
