Bored. So I said, hey, you know, for a forum this big (5.5k members?), and a car this awesome, we don't have many sigs.
I made this in 30 minutes... stole a tag off google images. Thought, hey, why don't I just make some sigs for those who have NISMOs, personalized with their specific model number, car color, etc?
It's so simplistic that it sucks, but if you want one, I could work a better example out.
Since the difference between a Nismo model and a regular Z (base/touring) look the same except for the body (and mostly the bottom), compare to my sig right below it. If an identically positioned Nismo were in it's place, it'd be hard to see anything (you might see the wing).
I could always make the sig just a bit bigger to fit in an entire side profile of the Nismo, showing off its body work. That would also give me some room to shove in that brushed aluminum plaque located in all Nismo's for the purpose of recording it's model number. Then I can shove other effects in too, I guess.
