What's your strategy for scrapping a car? I find people grossly underestimate the cost of car ownership mostly due to cost of maintenance and repairs at the end of life. It's so easy to keep bleeding parts and labour for longer than is economical.
EV motors typically outlive the rest of the car. Leaf is old enough that there's a whole cottage industry of battery repairs, replacements, and repurposing them for solar energy storage.
I've meant you don't need to worry about motors failing in old EVs, unlike engines that are the primarily concern in old ICE cars.
Apart from battery degradation, the other thing that may be the final nail in the coffin for an old EV (other than Leaf) is failure of HVAC. Temperature management is important for keeping batteries healthy when fast charging, and to prevent motors from overheating when you send them a quarter of a megawatt of power.
And the rest of the problems is the same like in any other car of the same era.
