Tesla, of course, has only recently changed their mind on this. I received this Tesla email on the 7th.
That is correct, 3rd party dealers are able to purchase out the vehicle but contacting Tesla finance at (844) 837 5285 OPT 1.
Best!
Now it seems to me the question in play would be, did you lease the car knowing this -- and were partly induced to lease -- because of this option? Would that have been a deal breaker? Hard to prove but just as hard to disprove. I'm not a lawyer and can't site case law. But, whether they own the car or not, maybe they can't just change a policy capriciously.
Apple a few years back had a sh!t-scandal with their "Error 53" where they just -- randomly -- decided that if you took your iPhone to an independent repair shop to have your screen replaced (eg) that the next time you updated Apple would wipe and brick your phone. The elephant in the room was Anti-trust laws, but part of Apple's reasoning was they were simply trying to provide a more secure software environment... by forcing owners to only use Apple repair. In the end Apple backed down (with class-action suits looming in the US and the EU) but one argument was that whether Apple had a legitimate reason or not, they couldn't change the buyer's expected user experience without notification. In other words, even if legit, it couldn't be retroactive.
