The look of the manual is fine. However, with the auto airco, it also comes with the vents for the rear seats. It is located in the back of the hand rest.
It depends on how important the rear airco for u. For me, I seldom take more than 2 people so I just don't care about spending that much money for auto airco. I think it's HK$8k for that option, nearly US$1100.
