Oh no, I'm already looking like a noob, accidently posting before I'm done and no edit button in sight.
I wanted to share that some of us get only one EDD. Maybe that will change, but there is a certain level of confidence that your account is behaving like everybody else's, and mine is not. I share the apprehension of getting the latest model with latest updates, but new cars are always being 'adjusted' in the manufacturing process, Our difference is we have a better knowledge of this and it is indeed hard to just sit back and see what happens.
My M3 LR is Blue/White/19"/No FSD, and believe me, I have considered changing colors, wheels, etc. and my wife often pulls me back from the ledge. Force yourself to enjoy the ride, yes, it can be as exciting as the destination, if you don't pull too much hair out.
