I will be doing this as a fun project at the Academy of Art in SF. I will post images of my sketches as well as clay models. Glad to see your input and interest! Forward-jutting nose, like a shark (it doesn't have to be as tall as the original 6). No B-pillar with windows down (frameless door glass). NOT a 2-door 5-Series (nothing wrong with the 5-er, but 6 should be unique). Let us know how it turns out and post your finished project here. Thanks.
