After configuration, my delivery date was projected to be "Sept-Nov 2018." The big mistake that Tesla made was to infer that I was actually going to get my car during the front end of that projection when they scheduled me for 9/23. The second error was mine alone, and that was joining TMC where in addition to learning a lot of excellent info about Model 3 ownership, I could vicariously experience ownership through the words and photos of the online posters and start wondering when I would get called up.
Technically, Tesla is has two months to deliver for me within that original window. It is the roller coaster ride that makes me want to throw up. I'm not going to cancel and put a deposit on a Tayman. I'm really REALLY trying to not pester the hell out of my DA or whomever will give me the time of day at Tesla but the suspense is killing me. I wish I would have never had an original delivery date and that I was still blissfully ignorant.
I also have to believe that the happiest owners are posting their biggest joys on TMC, along with the folks who rejected delivery for subpar quality and those who have been bounced around the worst waiting for delivery. The other 500k or so are out motoring and are too busy to post. Right?
the worst mistake Tesla is making is involving customers into their mess. Just don't assign the delivery until you know the car is there, or at least shipped. Is it that difficult really. That would be more akin to special order experience with any other brand. With my last special order the dealer called me only after the car was there and prepped for pick up. I couldn't care less about which railroad junction it was going thru and when.
