Not to cast a disparaging shadow on this discussion, but if you're 
concerned about aerodynamics, or gas mileage, go buy a Miata.  If you 
want a car with character, one that delivers the true visceral joys of 
open-top motoring, stick with the MG and forget about the mileage.

The most important variable would be air resistance.  You would use less
gas per mile at the lower car speed, because the energy needed to 
air resistance would be substantially less.
