Okay, so here's the story (I hope I'm remembering all the details correctly and in the right order).
My BIL ordered on January 15. His original delivery location was Dallas, but that was later updated to Tyler (can't remember if he was able to request that or if Tesla did it). He's much closer to Tyler. Like the rest of us, his EDDs kept moving all over the place and he was growing impatient. I found his exact build in Dallas inventory, but it was gone in less than an hour before he got my message. There was another one in Houston, which was even farther away than Dallas, but he was able to have it assigned to him. After an unusual delay, he finally got a delivery date, but the location showed Tyler. It turns out that Tesla forgot to change the delivery location from Tyler to Houston when he had the inventory vehicle assigned. That was updated and everything was in order for a Houston delivery. Well, he got a call from Tesla yesterday who told him the vehicle that was scheduled to ship to Houston was accidentally shipped to Tyler. They had scheduled it to be brought back to Houston, but thankfully, someone realized the shipping error actually worked out in my BIL's favor since he's much closer to Tyler so they left it there. The downside is there will be an unexpected delay while they wait on temporary tags to be issued in a different county than originally planned, but the upside is that he'll only have to travel 38 miles to pick up his Model Y instead of 211 miles.
