Happened on this thread. Don't know what the problem was with the original poster. FWIW, the SO and I ordered a MY LR on 6/29/2021 and we had it in hand September 24, 2021. Yes, the delivery date bounced around quite a bit; at one point, we panicked and got the cash ready for the thing, since we thought we'd be getting the car in late July, but September it was.
We did have an SA who gave us a bit of an assist when we test drove the car; and, when NJ's electric car rebate system got moved around, called us up and gave us instructions on how to order an additional Tesla; then, when the first one got a VIN, simultaneously assigned the car to the second order and cancelled the first. Paid of bit of money to Tesla to do that but the rebate from NJ covered that and then some.
We've had a M3 LR since fall of 2018. I find the SC's responsive when problems crop up pretty blame good. And the couple of minor blemishes on the new Model Y were fixed pretty blame quickly, too.
As far as raising the cash goes: The SO and I were both raised by survivors of the Great Depression. As such, we're both tightwads. We'd both rather save our nickles and dimes ahead of time, getting interest, dividends, and capital gains as we go, then buy a car, lather, rinse, repeat, rather than taking out a loan and paying somebody else interest. Yes, that meant that the first few generations of the cars we bought over the years were econoboxes, but not the later ones. And, what the heck, if one is driving 15K-20K miles a year, with solar panels on the roof, the savings of Not Having To Use Oil/Gas makes up for it all.
