Jay,

Why don't you just build a Kitfox? They burn 5gph and can go 110mph.
They are a lot better looking than an old Ercoupe, and the visibility
with plexiglass doors and turtledeck is awesome...

My friend has a Kitfox 7A that we flew to Oshkosh last year. It was
a long flight, but was fun nonetheless. For local flying or short
trips it is a great little plane.
