looks to me like the show judges wouldnt be able to question your car if you just allowed a grafitti tag artist to have his way on your car!
"Thats the way it came from the factory!"
I can remember my dad telling stories of coke bottles hanging by wire inside doors to cause rattles, and tools left everywhichwhere inside his cars (from the factory of course). There was a lot of dissension back then between union and management, and it gave foreign competitors a foot in the door, which they have since shoved wide open.
Not trying to change the subject, because tools and coke bottles are NOT doodles or names, but....they would add to the originality, especially if its the original coke bottle, or at least period correct!
