I started building my prototype last summer with the idea of going eco extreme with no regard to style and only aero in mind but I'm very impressed with how you accomplished aero and style. I planned on the same seating only with 3 instead of 5. I will have to post up some pics for some suggestions on aero improvements. It's the ideal teardrop shape for the most part and will be very difficult to produce I'm betting.
Oh and a bump for a progress update.
