OK using just aerodynamics how much MPG can you get with a:

Say 2003 Ford Crown Vic,

A 1995/2005 Ford/Chevy full size Van.

Or any car, how much MPG with just adding aerodynamics can you get, in this case, I saw a write up showing how much each of these things gave:

as in removing side mirrors,

windshield wipers,

door handles,

rain gutters,

roof racks,

then adding under belly pan,

rear wheel fender skirts,

if possible front fender skirts if not then large disk like wheel covers,

and lastly Boat Tails.

I remember all that was only worth around a gain of 5MPG.
