This indicates to me that that the estimated delivery notice on one's dashboard may now be driven directly by an intranet feed from the factory. That is, the estimated delivery month can bounce around as the metabolism of the factory ebbs and surges. So luck may not really come into it, so much as "noise" in the algorithm and the underlying fluctuation of the supply/production chain. Just a guess...
mine was changed just like yours however I had requested Feb to start with. If it turned out to be late Jan I would have been fine with that too.
I'm having the opposite problem. When I ordered, I chose April. When I confirmed, it jumped to February. :smile:
My date jumped to Feb 2015 from Jan 2015 as well. I called my Delivery Rep and he told me that Feb 2015 is a realistic estimate. He estimated that the car that I confirmed on 10/10/14 would not be built until mid Jan 2015 and delivered until mid to late Feb. 2015.
