This is entirely incorrect. You cannot permanently import or register a vehicle which has not undergone homologation. None of these vehicles have been certified to meet US safety standards and they cannot be imported permanently.
Nice ackchullay there, thank you for your contribution to the discussion. It is pretty clear that OP is referring to new cars based on context but hey who cares about context.
Simple and legal are different matters. There's a BYD parked in my neighborhood pretty often (Central Texas) with Mexico plates. I have no idea how "permanent" it is, and yet there it is.
