FWIW, I spoke with my SA in Walnut Creek,Ca just about 40 from the Fremont plant.
I went it to take another test drive since my first one was shortened due to my grumpy pregnant niece that needed a ride home from a doctors appointment, and since my girlfriend was with me this time.
The SA stated that they were down to 2 test drive cars since they were selling them for the end of the quarter push, they only had a model S in their boutique showroom, there was a model 3 and Y in the showroom previously.
But she said call her in a couple weeks when they get in fresh cars and she would let me take a overnight test drive since mine is already on order, sweet!
I ordered on 2/22/2022 original edd was August 2022, moved to 6/19 - 7/17, I asked her if she may have a better time frame, she checked and said mine would be a 2nd quarter delivery, probably late April or May, she said that was purely speculation on what she has seen and the info at her disposal
So a good number of test drive cars are being sold, probably a normal procedure to make the end of Q1 numbers better
