I've seen BMW M cars with triple-line pinstriping in the Motorsport colors- blue, purple and red. Looks really sharp on a black M car- there is a '88 M5 at my old office that has these stripes. Said car is in pristine condition and looks beautiful. That said, I prefer my cars w/o pinstripes. Even took the stripes off of our old Maxima SE, much cleaner look that way. Taka
