At present I am driving an 05 Honda Civic Hybrid, and unfortunately for the sake of the thread I no longer have any need for aero-modded wheels.

First aero mods are almost completely insignificant in the city, second given the extent of mods at once wheel covers account for maybe 5% and that would give .05x4 = 0.2mpg therefore a very insignificant gain. An even better gain for a vehicle like a all time 4x4 would be drive shaft and rear axle delete, would have seen 30 or more mpgs.
Again I'm looking for a clear analysis of the two different options, anyone with them already and can afford to chuck out the change to prove the significance.
