I'm all about the cool factor. I envision that as a tag at the last 3/4 of the quarter panel. Like what Alpina did with there solid stripe on the E12 only not as wide.
Start with a double pinstripe in the stock position. as the gold stripes break onto the quarter panel add a small break, then a block over a slash then start increasing the size. The tag could easily move up to cover 1.5" without over powering the lines of the car. The open blocks will help keep it suttle.
Cool Deco patten. I like the deco lamp shade patterns too. Ya, I'm out there...
