Our DS sent an e-mail over the weekend, indicating our car could go into production sometime in the next several weeks.
Seems strange that the window was that large at this point - unless there's another factor impacting production - such as waiting for parts to be delivered, or they are getting close to the 200K threshold and still working out which US vehicles will be delivered in Q2 and stay under 200K.
While our DS has been helpful - what we saw last year when we placed our S 100D order was that the DS didn't always have the most up-to-date information. We had 3 information sources to rely on during the order, production & delivery process - Tesla Account page, DS, and e-mails from Tesla. And those three sources weren't always in sync - and the DS wasn't always the most up-to-date.
For our S 100D, the car went into production faster than expected - was delivered to the local Service Center faster than expected, so at this point, wouldn't be surprised to see our car show up anytime between next week and mid-to-late July. Still hoping sooner, before we take several family vacations next month...
