Average lifespan of a car in the US is 16 years, warranty covers half of that.

Given the lowest acceptable threshold for capacity under some warranties (70%) and assuming linear degradation, a 16 year old EV would have 40% capacity (worst case). Given a typical range of 250 for EVs today, that would put you at ~110 miles on a charge.

Seems like it would be a fine car to me given the age. I'd also expect battery swaps to become more common as the industry ages, which will drive prices down.
