I ordered 5/26, it was 8-12 weeks ETA then. A week later they changed it to 4-8 weeks. Towards the end of June I emailed and asked Tesla if I should expect the delivery based on the 4-8 weeks or the 8-12 weeks when I first ordered, since I had not heard anything back. They said it was 'first come first serve'. On 6/19 I received a text saying they were preparing for delivery and to finish the steps on the web page. I had previously sent several emails to my Tesla support reps about being stuck on the financing part - it would ask me to fill out an application with Alliant Credit, which I had already done and was approved, but the web site did not see this. I asked if that would delay and they said no, its first come first server. About a week and a half later after not seeing any changes I emailed again, this time my Tesla 'finance' advisor responded and asked how much I financed. I replied, heard nothing back for another week, so I emailed again. Again, my Tesla finance advisor asked how much I was going to finance (... I already responded to that). I didn't hear back so on 6/30 I called Tesla and was transferred to a Houston location, the salesperson wanted to get me in a car THAT DAY, but financing was not lined up because Tesla had not responded to my previous emails about getting stuck on the finance part. The salesperson that answered the call, whom I informed about the problem, fixed the issues in mere seconds, I refreshed the Tesla website and it was fixed. The next day I was assigned a VIN.
And now more in response to your question:
I have since made payment transfer to bank and I am waiting on delivery, I have no been given a delivery date etc. When I asked the local salesperson he looked up my VIN and said it was still on the factory line (18XXX) and I should expect it towards the end of the month. He hinted that it is kind of good I am getting one that is just not getting made, he said they are slowing down to fix 'some issues they have had'.
