An easy way to determine your car's aeromod potential is to note what your mpg is when drafting another vehicle. This is the mpg that you could get if you thoroughly aeromodded your car to reduce its Cd.

In addition to improved mpg and the equivalent of a horsepower boost at higher speeds, two side effects of reducing your Cd is that drafting has less effect on improving your mileage and the non-fan assisted air flow through the ventilation system is diminished. Both of these require the presence of a high pressure zone at the front of the car and a low pressure zone at the rear of the car to manifest. As you lower your Cd, you reduce the pressure differential between the front and rear of the car.
