Alot of people mentioned things I would never think of.

But I know I would really like...

1. A/C seats
2. More comfortable sport seats, these are ehhhh
3. An electronic read out of speed, where the temp gauge is.
4. Better paint

 

as mentioned.

COOLED SEATS

 

couldnt have said it better

 

folding mirrors
rear/front parking sensors
3 second blink by tapping signal stick (mine does that)
reverse: side view mirrors down

 

Mine came with folding mirrors?
but not the 3 sec blink, nice mod

 

when you turn off the car your seat and steering wheel move back.

 

Lots of good ideas here already...

1) Signals on side view mirrors
2) Auto folding sideview mirrors - after shutting off engine or opening your garage.
3) TPMS that is actually useful. (I contend it is barely useful at all now - I had a failure in one sensor, but since the useless TPMS doesn't display the tire or pressure, I couldn't identify the problem on a long trip)

 

Aint' gonna happen, the rear passenger's leg will be crushed.

 

What I think is a must and im surprised that we dont have it: 60/40 split fold down rear seat. The acoustics are so much better with the back seat layed down but I hate laying the whole thing down I just want one small section(referring to after market subs) Also cooling front seats. Tilt side mirrors when in reverse. And an engine thats mod friendly.

 

Man I can't believe nobody has mentioned auto dimming outside mirrors. I really miss those from the IS350.

Those, the forward-facing LED overhead maplights (so you don't blind yourself like the G's ridiculously bright ones), and (as others have mentioned) the rain-sensing wipers.

 

placing the fog lights in the lower section of the front bumper instead of those black net things would make the car look wicked at night.. i personally think the start button is too cheap too. i also hated the exhaust tone but ordered my catbacks and awaiting their arrival so that prob solved.. also the area on the doors with all the buttons could be improved big time looks wise i think its too plain
however im in love with my G haha

 

Headlights that turn on automatically when you turn on your windshield wipers. (Pet peeve of mine when people drive when it's raining without their headlights on)

And as others mentioned, tops on my list would include:

A conservative turbo, would like about 60 more horses and 60-80 more lb/ft of torque.

Better paint.

AC seats.

Auto dimming side mirrors. (That is a great feature that Lexus has).

 

I wish it was as light as the previous gen coupe.
