>the only maintenance

Suspension and tires are the biggest items for EVs. The twist is cheap owner can neglect those and keep driving past service window with ripped bushings and clapped out tires until hitting that magic 3 year goal, then you buy used EV in need of 4 of everything.

You can see the tires, at least, so that will just come off the value. And if you turn in a lease at three years with clapped out tires they'll make you pay for new ones.
