I believe I just missed out on the next-generation seats. I remember asking if I could upgrade them by paying the difference, but it was too late.
I do have a late 2014 P85D and yes, it does take the corners flat. I describe it as feeling magnetized to the road. The 3 is most definitely a Tesla, but you can feel the lighter weight, especially in the corners. I’d say it’s more fun and sporty, while the S is more commanding. The S feels like a kind of modern electric tank. Not that it handles poorly but you feel the size/weight and that’s both a positive and negative. Before the 3, I loved it. But now, for everyday driving, I prefer the 3. A Performance AWD 3 (preferably with a hatchback option) would be my ideal car. Unless, of course, a refreshed S nails it and becomes that with all the 3’s improvements and more. (I’m talking stuff you’d see in a genuine large flagship sedan like an S Class Mercedes, like active bolsters, better sound system, more range, better active suspension, even better/faster UX than the 3, ventilated seats 2.0, night vision, soft close doors, built-in window shades, laser or some form of advanced projector headlights, and yeah a HUD.)
This 3 was always intended to be a stopgap for me while waiting for the S to refresh. I didn’t expect to like it so much. I thought it was going to be a noticeably “economy” Tesla. Instead, as I’ve mentioned elsewhere, it feels like the platform is the refrehed Model S. While you can’t beat an insane/ludicrous launch, it’s not nearly as exhilarating after doing it for three years. I mean, sure it’s fun and helps with merging, but once you’ve taken all your friends and family for a ride, it doesn’t feel as important to me. (Even the RWD 3 has plenty of power for passing at highway speeds.)
And then you consider it’s less than half the price of the P85D (when it was new) with more range, the latest Autopilot, a faster user interface, better wiring and major system redundancies, no fuses (using more advanced MOSFETs), keyfob-less entry, more advanced HVAC, general user refinements (better phone holders, door storage, coat hooks), brighter headlights, and noticeably better sound system. The worst thing about the 3 is how it makes me feel about the S I’ve loved so much.
