Agree with the OP's list and I'd add (though being picky), more low-end torque, believe it or not, it's a little soft below 3500 rpm.
Heads Up Display would be awesome, that's what me and the fellas here think anywaysI will start the list with a few:
1. Launch Control
2. Larger NAV screen from the GSF
3. Weight Reduction
4. Folding Mirrors
5. Adjustable Exhaust (quiet to sport mode/loud)
What did I miss!?
