How to make NFS Underground "Intro Supra" in OPS2M Jailbroken Demo

Can't do the fancy colored decals like in the Intro, because those were either removed, or they didn't exist in the first place.
Nonetheless, this version of the game has a wealth of cut content, including numerous vinyls that never made it into the final game.
Also, painting specific parts has not been implemented yet, neither was applying vinyls over carbon fiber parts still available (if it ever was).
