MP3Mike is correct. You do not own the leased vehicle and Tesla has the right to refuse to sell to 3rd parties, and at any price they want to 3rd parties. In that case you’d just have to do the buyout yourself and sell it to the dealer afterwards and depends on which state you are in there are tax implications which is why most people prefer to have the 3rd party dealer do the buyout. That’s probably your best bet right now to get it settled. Sorry can’t really help your situation but just reliterating the issue involved with leased buyouts these days.
Some banks, like Ally, even have different buyout quotes for different parties/purposes - the lessee quote, dealer for inventory quote, and dealer for lessee quote, all in different amounts.
