Checked in to see if the production schedule had changed, and indeed, I'm now told my GGT is scheduled to enter production in the "third week of September" and will be ready for delivery 30-45 days after that. What prompted my question to my SA was the conversations on here regarding the Power Package (plugs) and the smaller wheels. I specifically asked if those features might be delaying production, and that went unanswered. Which, honestly, I took as a "yes," given the apparent 3 week revision in production.
My specs were GGT AG, Stealth, 20/21, 5 seats, Yosemite, DD Premium, Sound Pro, no towing, Power package (but no HUD), Dynamic Handling, and Comfort/Convenience.
