Mine never gave me any indications. Week 7 came, on a Monday, they called saying it's expected in later that week. Then they called me later same day and said it had come in that afternoon, haha.
Your dealer should be able to track your car very easily- after ordering, mine told me when it was scheduled for production, in production, on a rail train, and when it had been transferred to truck for final delivery. He pretty much nailed the delivery time... it came in a day earlier than his estimate.
I was very satisfied!
