The question being: Will you be able get an U.S. or Japanese EV then which is not based on Chinese technology? And does it make sense to keep up a mindset adapted to internal combustion engines in an era of electrical cars? Do you know which parts usually wear out and fail in EVs, and after which time? The Nissan Leaf is not a good example. It was prone to battery wear far above the expected rate. Newer EVs have battery wear far below the expected rate. And do you know when the innovation in EV design slows down so far that it makes sense to keep parts for 15 or 20 year old cars? 15 years ago, Tesla was selling the Tesla Roadster, basically an EV conversion of the Lotus Elise, co-developed by AC Propulsion and Lotus. Do you need spare parts for a Tesla Roadster? The first EV to ever sell in large numbers, the Tesla Model S, is not even 15 year old right now.
My prediction is that you will buy an EV just because they will be cheaper to get and cheaper to operate than a comparable ICE car, and repairs far into the future will be a very second thought. At the moment, we have price parity, that means the same amount of money gets you the same amount of new car in both worlds. In five years time, this will also be true for the used car market.
