Hi Olivia/GodzillaGTR,
Welcome to the forum (although I've just signed up).
Have you seen this National Geographic documentary about the production of the GTR?
I just thought it might help with the inspiration. I found it quite interesting, and I like the contrast of a mass-produced supercar over what most of the competitors are doing. :~)
Hope you enjoy (if you haven't already seen it).
Harmo.
