Gulfstream visitor

Here is a picture of an N-reg [USA registered] Gulfstream departing Wellington earlier today. Unfortunately I was unable to capture the full registration [another photo has a partial reg], so I am unable to confirm if this is a G-V or G-IV model [I believe it to be the G-V model]. Any comments on this would be appreciated.

You'll notice a couple of things in the photo. Firstly, although it has just taken off, it's already well up in the air - presumably because of light weights as well as good overall performance?. Secondly, look closely [click on the image for a larger version] and you'll see that it is polished all over. Wow - these people know how to look after their aircraft.
