So my suggestion is pretty simple, I'll start explaining
Well, we got a feature that's the crew 'logo' vinyl in our car, so my suggestion is, crew leader ( who created it ) would ask someone to make or he would make a crew vinyl and only crew members would be able to use and it would have it's own space like, in vinyls>Layer etc, > Crew
To get it added ingame there should be a board in the forum which contains with a thread for crew vinyls requests
And the crew leader ( as I said, who created it ) would request there and the "manager"(which normally is a moderator) of that thread would add it ingame
This wasn't in NFS:U1 or NFS:U2 but since we got crew system why not adding this feature to it?
