Critical point - thanks for making it.
Jim: I'd recommend testing a cardboard & duct tape prototype, to assure yourself a "good" version is worth the effort.
EDIT: however, and this is really important, we can't forget the Insight doesn't share the Metro's ICE technology. Any aero improvements to the Insight widen the lean burn window. So an Insight may not need as much of a Cd improvement to equal the Metro's 15% fuel economy improvement.
Mike may be able to speak to this since his car is now lean burn equipped.
