I'm not actually answering your question, but I'm in a similar situation. I have the same 11/20 build date and got the VIN from my dealer last Thursday - it popped up on NetStar. Now it all depends when it gets on a ship, and what that ship's schedule is. Then the visit to the VPC, inspection, and delivery to the dealer. MB uses two shipping companies, Wallenius Wilhelmsen and HUAL, which you've probably seen from other posts. Wallenius Wilhelmsen's schedule shows a ship leaving Bremerhaven Nov. 25 and getting to the west coast Dec. 19. Oh please Santa!
You're in better shape on the east coast, of course. Your dealer should see your VIN on NetStar soon if not already, and within days after that, shipping details should appear on NetStar. Good luck!
