Nice patriotic theme dude! Some tips though... Don't lose the shadows on the default skin or paint some of yours in to get rid of the cel shaded cartoony look. But if that was what you were intending then nice!
Actually he's on the correct section. He's looking for the RedBull F1 car skin (RB4) not the LFS RB4. Check out http://en.wikipedia.org/wiki/Red_Bull_RB4. He's also not requesting for one, just checking if it's already available.
Anyway... Scania, I don't have one for 2008, but is it very different from the 2007 one? I remember an F1 2007 skin pack floating around the forum.
