Why do used electrics drop so quickly in price? - eviltoast

It’s been years since I’ve checked the used electric market, but I’m seeing cars like the Hyundai Ionic 6 or Polestar 2 for low 30s, where as they were in the high 40s or mid 50s new a year ago.

My suspicion is that:

  1. Normal car depreciation when driven off the lot
  2. General fear of batteries wearing down prematurely, even if the car has ~10k miles
  3. Any applicable federal rebates or otherwise have already been claimed and can’t be claimed on used vehicles(?)

Is there any other reason why these drop so quickly? Would buying one be considered foolish in anyway?
