Just got off the phone with my DA. My VIN has indeed been assigned and he expects delivery before the end of the year. Wouldn't specify exact timing, as the car still has to go through PDI and then get shipped to Denver, but production is complete, and I'm pretty confident it will be in my hands sometime in the first half of December. We'll see. PDI could always unearth some major issue, I suppose.
So when you do get that email about applying for financing, I'd say that's very likely a sign your VIN will be not far behind.
Also, he didn't say, but from the looks of it, white is indeed the next color after silver. Not too many whites on our tracker, so I do think they will get through them quickly and move onto whatever color is next.
Best wishes to everyone still patiently waiting. I really do think they want to push to get as many of these cars delivered as possible.
