I've had many Bay window buses, but damn it, I was never lucky enough to find one with that rare Porsche engine option. I bet it also has the optional Weber carb as well!  Where do people get these ideas from? Related note, a few years ago, right after the movie Cars came out, I put my last Bay window bus in a local car show. I was amazed at how many small children pointed at it and screamed "Fillmore!"           Jeff
