Just by looking at the NACA duct, I can tell it has fresh clear on it. The factory clear is not that shiny and it does fade and crack around that area. Why Nissan did not paint the duct with same colour as the car is beyond me. Perhaps they have a good reason for this.
Like Beer has mentioned, the bolster would be a concern as well. A big guy would definitely accelerate the wear and tear.
Personally, I would never judge a car by it's kms, especially an import and more so, a GT-R. Most of them seems to have super low kms which is total bollocks. Only a small percentage would be genuine and would believe it more if it comes with history.
Looks like the RH front guard has been removed as the bolt heads appear to have little or not paint in them, but it might just be the picture.
A white engine bay is good to inspect. The more kms she's travelled, the more "off white" colour you can observe. You can also tell straight away if there's any repairs done because a newer white respray will never match the old colour unless the entire engine bay has been resprayed. I've seen it once before where the whole bay was resprayed and was just too shiny to be a factory job.
Bit of surface rust on the rear diffuser support bracket. Mine has no signs of rust and it's still original. I would look further underneath for potential rust issues.
