I feel like there's an information asymmetry between the used car buyer (who has likely never owned a Tesla before, and certainly doesn't know the history of the vehicle he's considering purchasing), the seller (who may specifically be aware that the car appears to have functionality that could be revoked at a later date), and Tesla (who have records of what has been paid for).
What are the right questions for a buyer to ask in order to ensure they're not left in this unfortunate position?
