Heh, the car's from one of the Admins from the Dutch Nissan100NXclub :P. He has a particular taste.
Since SR performance parts are pretty hard to come by in Europe, most go for looks. In this particular case, it was styled in the Rat Look. That usually includes a rusted or flat black paintjob (this one being rolled), rust coloured parts (usually hood), and a roof rack, with stuff on it.
It's usually found on German type cars, but he wanted to do something different on his NX.
And those roofracks can be pretty handy :P.
