Hey! I am in Austin as well.We all deserve a less wait time so I’ll keep my fingers crossed you’ll get it the same time me!
Long time lurker, first time poster lol. My order date was June 13th. MYLR 5 seater, MSM, no tow, standard wheels. My EDD is also similar to yours, Aug 12th - 29th (was all over the place but has been settling in this range since last couple of weeks). So I wouldnt be surprised if they are just scheduling it based on how many cars are headed to what destination, and seeing more people with similar EDD gives me a bit more confidence that this will stick.
I also went into the delivery center on Research Blvd a couple of weeks ago, and the guy there said that I should expect my VIN around Aug 15th ish, and the delivery will be 10-15 days from that. He also said that they do an inspection once the car arrives at the delivery center, and then deliver it.
