My initial idea was to change the colors on Montoya's car. Maybe as a alternate for night races. Although the base and number placement sucks now as I see it with a little distance I'm not willing to change it.
While I was at it I thought a white car for McMurray would be a nice idea as well.
SRD temp, Sim Racing USA scenes, some BOTW logos, some via Google image search, VERY MUCH scratchmade stuff.
