I stopped at the dealership that I'll be taking delivery at and asked some questions since I was in the area Saturday night (it's pretty far away). In particular I was curious about how the trade in process works, as the dealership is about 90 miles away and my trade in is in not so great shape.
They asked when and what I ordered (6/27, AWD) and the person I spoke with said she would expect I'll get the details on trade in within the next two weeks. She said that deliveries had greatly accelerated recently, and that almost every 3 they were delivering was significantly ahead of its original delivery time frame.
I believe we'll see Ps start arriving soon, and AWD cars start delivering quickly after that. My original guess was I would get it at the end of October, now I'm thinking there is a real shot of August.
Also, just for the record, she acknowledged they didn't really know in the AWD / P versions of the car yet and things could change...
