rear

You might want to study contemporary urban and intercity buses as they all have rear heat exchangers.
Also,Ford's Probe-IV concept car of 1984 had the radiator and condenser ducted into the rear quarter panels,with electric fans which could push the car to 4-mph if I remember correctly.
A thought.If you were to pull a perfect draft behind a semi and the mpg was so remarkable as to compel you to proceed with the project,then great.However,there may be purely stock cars whose mpg already exceeds the theoretical maximum which the Neon demonstrates in the draft.
