469 days after ordering, today was D-Day. The DS unlocked the MX and allowed ample time for me to inspect on my own before clicking the Accept button in the app.
The only issue I had was connecting my iPhone via Bluetooth. When I asked about this, the DS told me that Bluetooth connectivity does not work properly until the Accept button is selected. Paint and panels look good. No yoke worm. Interior trim looks good. The only minor problem so far is plastic trim not glued down over the left rear wheel well, adjacent to the FWD. Other exterior plastic trim perhaps a bit loose. All doors and windows open and close smoothly and seals look good.
I was surprised to find the portable charger in the boot. Hitch receiver was in the frunk. No fobs. I asked about purchasing a fob, but they had none is stock and the Tesla Store shows out-of-stock for MX.
Overall, the delivery process was smooth and efficient. My DS was unobtrusive and understanding. After departing, I found the steering to be stiff, but then I discovered that steering was on sport, and when changed to comfort, the feel was the same as my old MS. Even though I have been driving a Tesla for 6½ years, the learning curve for the Refresh MX is steeper than I anticipated, but an enjoyable exercise, nevertheless.
Thanks to all on this forum for the info and support. The Google spreadsheet is an amazing resource. Thanks, also, to those who authored the comprehensive inspection checklists. Now I need to finish the calibration process, get a score sufficient to enable FSD, and enjoy this amazing vehicle. The long wait was annoying, to say the least, but worth it, in the end. Starship, indeed.
