Passenger seat adjustments. I and my wife are not tall people so the driver's seat is always up to the maximum height. Not having ability to adjust height in passenger seat is frustrating, my wife even bought a pillow

Would be happy to pay more to have this feature though don't think adding one more control would cost significantly more.
Steering
wheel doesn't have a big range of movement.
Would not mind to have touch screen in addition to the knob. Not a complaint, just a wish.
Ability to view tire pressure as one of the menu choices. Well, I haven't gone through the manual yet, may be it is there somewhere.
No complaint in ride, very smooth, powerful, quiet. Sometimes have to fight with my wife, she really like to drive it
