Thanks for the comments people!
Regarding GCC spec, I believe this only involves the dual AC and standard window-tint-reflective. There is an additional AC unit behind the seats. Interestingly the standard (front) AC unit seems to give up after an hour or 2, but the back one happily boosts along. In full on sun and 40+ (Celcius) you can't have the AC on max because it would freeze your knuckles (and other bits).
I will check if there are any other differences for the GCC. I could imagine another type of air-filter but not sure.
Number plate was mounted a day after I took the pictures. I figured having a long plate with sharp edges in the cabin ...... not the best idea ever
