I have thought of building my own car for a while. I can have a 91 Sprint for free, I just have to get out to the guys house to pick it up which I would use for the powerplant in my car. I would have it look something like the Arial Atom but with a Metro engine. I have read that the Atom gets in the mid 30mpg range which is amazing considering that it has 250 to 300 horsepower. Imagine that same car with a Metro engine and improved aerodynamics.
