Sounds like you have new information that wasn't available when I ordered. I got the X-Plan discount. The sales guy did say that I would also get all incentives "offered at the time my car arrived".
I gave the dealer a $1,000 Deposit Saturday, 8/18 and they gave me a printed copy of an "Order Preview" which show the costs but not the order number or dealer code. They said they will not have the order number until after the factory converts from 2017 to 2018 production. Does this sound...
