I just called the Cincinnati location. They said they don't have a VIN assigned to my order yet, but they're expecting a bunch to come in in two to four weeks. It will take two weeks for the vehicle to arrive there after it's off the assembly line.
Bottom line is end of September at the very latest, but could be earlier. How much earlier, who knows?
I was told that here in Maryland, all vehicles are coming in September- at the latest. VINs should be coming in a couple weeks. Haven't received any texts. Ordered a SR+ solid black, black int, 18" aero, autopilot.
