Couple of thoughts I hope are helpful to those waiting.
1) A “Previn” is not a VIN. It will not have the same digits, etc as a VIN. It’s something Lucid uses internally. The actual VIN will appear buried in your dashboard, usually during production unless you’re taking an inventory car. Again, though, if it’s not actually produced, no one outside of Lucid and you will know the VIN.
2) SW Update - some cars show this early and some have an error message right up until delivery. Our first was the latter, though our in production GGT is showing software updates now. Again, seems random.
3) Knowing if it’s done - if it says “Preparing for Delivery”, it’s complete. And likely past the factory gate. Any other status and you need to email, text, call. All the interim internal status changes are only visible, and only in parts, internally to folks at Lucid. Also, up to this point, the general rule of 30-45 days from “in production” to actual delivery has been accurate. That said, there are plenty of folks on here who’ve been “stuck” in production or preparing for delivery for much longer. That seems to be a less frequent occurrence as production has ramped up.
