Alright, now for a few updates.
Delivery appointment for us lasted maybe a little under an hour. We looked the car over fairly well, though didn't check every tiny detail. There were a couple of marks on the headliner and a scratch on the decor trim where the cupholders are, but otherwise looked pretty flawless. We felt that was reasonable for being slightly used. Signed the paperwork to accept as is, got a couple of complementary Tesla shirts, talked a bit longer, and then we were done. I actually stuck around briefly after pulling the S out because they had a couple of X's in the lot, I had never seen one before outside of pictures. They were nice enough to give me a quick look at it. Then we were on our way.
The car is awesome. Really happy with it so far. I was definitely rocking the Tesla grin as folks have been calling it. It was interesting driving the P85, as previously I had only test driven an S85 and a P90DL. The P85 feels a little angry compared to the smoothness of the other two. It seems to have more power than the rear tires know what to do with, and the traction control definitely works harder in this car (note: it has the Michelin Primary tires).
Highs: Performance, style (interior and exterior), touchscreen display, as a non AP car I really like the speedo, profiles (never had that in a car before), rear facing seats (really love how nicely they fold away, and the kids absolutely love them as it turns out), steering wheel controls with configurable instrument cluster, no exterior whip, wart, or fin antenna, NO SIGNIFICANT WIND BUFFETING (at least none I have noticed so far; it was terrible in my last couple of cars), and my knee doesn't rest against the center console in this car (my last car I kept a pillow in the car I would put between my knee and the instrument cluster), great rear camera, good parking sensors (so far).
Lows: No auxiliary audio in, USB audio support not as good as other cars, slow browser (though since most cars don't have such a feature at all, not sure I should count it as a low), weak wifi reception.
All in all, I thought I would really love this car, and turns out I was entirely right.
