Let me say this from experience. Right now I completely understand your pain. I think Tesla has issues and this entire process is disappointing. With that said once you see your car and sit behind the wheel there is this strange thing that happens. Your mouth starts to smile from ear to ear and you have so much happiness that nothing Tesla does matters. The car is incredible and will erase everything in your mind about the point up to that point you sat in that car.
Having driven a 3 several days already, I am well familiar of what I'm missing out on
Congrats on getting a great ride, small issues and all!
