Better throttle response, like the 4th-gen.

Automatic climate control, like the 4th gen (you had an option of setting the temperature, but adjusting the vents manually - useful for places where it can be 24 degrees at 7am, and 50 degrees by noon, like the north east of the USA)

Keep physical buttons/knobs for audio and climate controls (i.e. don't move them to an LCD panel).

Torsen center differential standard or make in an option for the TRD range (full time 4wd is useful for places like the north east of the USA,where road can be a mix of ice, slush and dry pavement), like the 4th-gen.

Remote Auto-down rear window, like the 4th-gen.

LED, auto-on headlights.

Apple/Android compatible stereo.

Gray/Beige interior color option on the TRD models (because it hides things like mud, sand, dust, and dog hair better)

Better cargo area storage - e.g. side/wheel well nooks with covers, like the 4th-gen.
