3rd baby on the Way need a bigger car. The new R1S reservation delivery date is too far out (made the reservation last month), I also have a reservation for Tesla model Y , 7 seater, I really prefer not to settled for that lol. I see some people are selling their reservations on here, how does it work? Are reservations even transfer able? I don't want to spend 1000s of $ and end up with nothing. Thanks in advance.
