Welcome aboard. It sounds like a wonderful price for a great car.
Not sure what the VIP model has, but I'm guessing DVD playback and reclining rear seats like the USDM cars have in the premium package. Please post pictures when you get a chance to.
To get a copy of the manual, just type in "2009 fuga 450gt owners manual" into Google. When I do that, what I see is an infiniti manual - very similar but not quite exact for the Japan market models.
Another thing that will help you with the ownership, whether you repair your own cars or just are curious about how things work. Those can be found here:
