Two-tone blue/silver outback. Planning to make this thing an off-roading beast as well as a gas sipper, not a gas chugger. Installing a sound system in it very soon, because the stock one is horrible and can't handle my music. Or anybody's for that matter.
K&N Air filter. Gotten me almost 1mpg.
Wheel skirts, front and rear
Under Tray if I don't get a full body skidplate
Aerodynamic additions to the front bumper with a hole for the CAI and an extra hole for added air, for when I go off-roading.
Non-stock MPG reader, whatever those are called.
