Recently had my car at service for 3 days and the gave me a 2012 Model S P85 wth ~33K miles on it. The car was pretty "base" it felt, aside from air suspension...and I say that because it had no AP or TACC, though I'm thinking those did not exist back then? • The air suspension was great, and it's kind of ruined the standard suspension in my car for me now. Not so much the ride quality, as it was pretty comparable, but the way the car felt. With the air suspension, the ride felt smoother as there are not as many vibrations in the steering wheel and especially floorboard. With the standard suspension, you can feel the tires against the road (even if its no a harsh road) - the air suspension felt more luxurious. • The P85 performance was great, definitely noticeable difference in acceleration. Kind of liked that too. • Tesla has come a long way on the interior. Maybe may not feel that way because overall its the same but it definitely is not. The seats in the 2012 were terrible compared to the Next Gen in mine. Not just the bolstering, but the design. Beige leather with random alcantara inserts and random grey bead stripe (or whatever you'd call that). Then the mix of chrome AC vent trim surround with aluminum around the main screen looked terrible. Their choice of dash wood was also very bad. • Dual motors in my car are worlds better than RWD of the P85. Im very used to just stomping on the pedal and there is no hesitation, no ESP kicking in. Not so much with the P85, it cut me off a few times when pulling out of a parking lot making a left turn and stomping on the pedal.
