I havent ridden in the new nav yet, wish i did. The suspension is the same but tuned different. From reviews, it seems the nav is tuned a bit softer than the expy, which is crazy as you probably know the expy is soft as it is with the ccd. The nav system is adaptive so it changes on the fly or suppose to, im not sure if the expys do that. Theres a cpl of people who have navis here, one says he feels the difference in ride.
As for color, white gold or red would be my color of choice for a platinum.
