One use case I can think of might be as a way to drive a Tesla now without having to wait a couple years for the supply chain issues to die down. I waited 9 months for a new one, and according to the guys who installed my charger a lot of people pay a large premium on lightly used Teslas just to not have to wait 6-9 months for delivery. All I can say is the wait for a new one is worth it. Pretend you have car payments already and set those payments aside every month. Put all of that towards the payment upon delivery.
