I tweeted Elon, haven't heard back yet, but at least it's out there. I actually got the car after some more delivery confusion. I went through a lot of issue getting it, BUT it's AWESOME. Everything I was hoping for in a Tesla: fun to drive, head turner. It's the future for sure.
I talked to a designer (I think helped with the windshield on the 3) who was helping with deliveries about the buying process. He said Elon knows it's broken and is working to fix it. Next year cars will likely be delivered to your home instead of you coming to the delivery center. That's the goal at least.
Hang in there with the delivery challenges, Tesla will eventually get it right.
