I have a '94 and was curious, do you think opening the rear windows, which just vent out an inch and a half would be benificial or harmful for mileage. Right now I leave my side windows 3/4 up to help with aero, but don't know if that vent will allow more air in than is going out or something along that line. Whatcha think?
