I guess if you have free solar charging.
She does, and I suspect that it will be become more and more common as the years go by.
There is always some randomness in vehicle depreciation, but I don’t see the Tesla being much worse than whatever else she would have bought. If your keeping a car for 200,000 miles residual value isn’t a big factor in overall use cost anyways unless it’s something collectible.
As to comparisons, I don’t think to be fair you need to compared the Tesla with only 75% battery life to a similarly hammered old used car. Sure a 20 year old Toyota with a quarter million miles may not have needed much, but just like a similar age Tesla is going to be pretty beat and would need a lot to “freshen up”
My old Prius was still driving at 280,000 with only a few thousand total in repairs/maintenance but it was very different from when it was new at that point.
