Interesting cool look, like a WWII fighter's fuselage. Nice photos too. Filtered and cropped and bordered.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
When I saw the pics, it reminded me somewhat of this guy's reverse trike: http://www.youtube.com/user/lightrose100/videos
Could be similar mechanism, although the information in Lightrose100's videos aren't that informative.
