The inside delivery specialist did not elaborate but imho she is referring to those customers that got the emails for March 2020 delivery and has gone through the process of having orders confirmed. I would assume that this refers to those that had an “Motor Vehicle Order Agreement” in place which makes your $2500 or $100 deposit non-refundable.
Im also hoping that this is the case but again just as the Tesla motor vehicle order agreement specifies in its language that “The estimated delivery date of your Vehicle, if provided, is only an estimate as we do not guarantee when your Vehicle will actually be delivered. Your actual delivery date is dependent on many factors, including your Vehicle’s configuraon and manufacturing availability.”
Im sure Tesla is going to do whatever it can to push for a lot of deliveries as the 1st quarter ends. This is supported by recent internal email Ive seen asking for employees to volunteer to help in delivering vehicles the last two weeks of March.
