Neil,
I'll grant you that the Boxfish model is aerodynamically very good, but I wouldn't use it as a starting point. You should consider it to be a demonstration of the fact that tapering a vehicle in from both sides and the top gives excellent aerodynamic drag. Start with as little frontal area as you can get away with, and work your way back from there, ending with as small of a trailing wake as you can.
You also have to realize that a clay model with a Cd of 0.095 will produce a car with a much higher drag coefficient.
The blue model would not be roomy inside. I'd say it's the basis for a tandem two or inline three seater.
