There has been a similar thread to this one before:

But I'll list up my items again:
Keyless Go/Start (option at least)
Instant fuel economy in trip computer
TPMS standard
Selectable suspension settings (comfort, sport, etc) - ala Touareg, GX470
Lower suspension automatically when put in park (user selectable)
Altitude available in on road mode on nav
Reclinable rear seats
And things I wouldn't change:
Exterior/interior styling (although they could make it a little more luxurious)
Transmission
V8 engine
Air suspension
Sunroofs (multiple ones)
Great third row
Great interior volume
Great ride
Great offroad ability
Terrain Response System
Key fob
Electronic Parking Break
Excellent Nav system
Easy to change air filters (if you've owned a V8 Touareg you'll know what I mean )
Excellent Xenon headlights
Nice heated windshield
Available rear heated seats

Edit:
One addtional improvements:
Greater than 4 digits for the altitude read out on the Nav
