ventilated and more comfortable seats would be great... however, these are the things I would value much more:
- better suspension tuning, the rear seats of my Model 3 are super bouncy when going over uneven roads/bumps ; probably the "roughest" suspension of any car I've driven. again this isn't the Performance version - normal # AWD LR...
- better sound insulation ... wind noise gets bad above 70 mph
- keep gear shifting as stalks and not touchscreen, same goes for signaling
- rear cross traffic alert
- bring radar back for TACC / AP in order to cut down on phantom braking
- inrease range of Model 3 AWD back to the ~358 miles it was before the latest version dropped
