Hi - we’re purchasing a Tesla with FSD paid by original owner. How do you know or is there a way to check / guarantee that the seller hasn’t already started the process or isn’t just going to transfer the FSD for the new one-time FSD transfer that Elon is offering once we buy it? It says that they will not do the remove capability from old car until up to 1 week before new car delivery. So what stops someone from processing the transfer / making you think you’re getting an FSD vehicle and not telling you about it?
