Got another call from my DS today, he said they will be able to hit my delivery window, despite what the other DS said yesterday. Let's see....only 10 days left for the close of my delivery window.
If it helps, I got my VIN Jan 30(I called each day at start of window) and my car reached the Chicago service center today. If VIN is issued at entry on the line then it took about 4 days to build.
