I'd go with:

(1) the fully adjustable, power front seats, with lumbar support; heat could be an option

(2) better stereo system

(3) better rear-view camera system, I hate the "fish eye", I can't tell when I'm about to hit something - perhaps have it switchable from "fish eye" to normal view, so you could use whichever is needed

(4) All-wheel drive as an available option

(5) different controls on the steering wheel - I'd prefer having stereo power, and a "mute" button, and climate fan up/down, and losing stereo "mode" and temp up/down (or button could do temp if in "auto" mode and fan if not)

(6) sun or moon roof option

(7) "electric only" mode, with a bigger battery pack

(8) I like the roof solar panel option (but it would have to have a built-in defroster to melt away the snow and ice!).
It is trivial, I admit, but it would also be nice to have a switch to tell the car "there is no passenger", so the seat-belt beep/flash will be disabled when I pile my junk (i.e., 30 lb. briefcase) on the seat!
