Guess what!? I also ordered mine the morning of March 31 2016, lining up at the Tesla store early in the morning and also had a Model S for 4 years. And I do not give a rats ass if I have to wait another few months before I get it. I was perfectly fine and did not expect it before Christmas (since my estimated delivery window was Sept-Nov and applied Elon-time adjustment to that), UNTIL the delivery specialists (4 different one) started to contact me and started telling me each a different fairy tale with imaginary locations and time-frames. Yet, I was willing to jump through all the hoops they threw at me trying to give them my money before Q3 ends, but they managed to lose my car somewhere in delivery logistics hell....
TLDR: I do not want your or anybody else's sympathy, I do not even need the car for at least another year (we have 3 other cars for a 3-driver family).
For the last time people, try to understand: I am NOT screaming because I did not get my car.
I am worried about Tesla losing a very nice advantage over other manufacturers: the much better buying experience, which was an extra advantage (on top of better cars) Tesla used to have.
