*Aero drag reduction would provide the greatest savings on the HWY.Around town it wouldn't mean diddly-squat.You'll have to consider your needs 'n see what might fit in.NASA got to Cd 0.238 and had still left some fruit on the tree.
*Weight reduction is kinda meaningless in all-highway operation.Adding a half-ton to my CRX only cost me 2 mpg.Around town,weight savings WOULD mean $ savings.

If you can find "golf ball style" body panels with built-in dimples (or create them yourself out of clay), that will increase mpg 30-60%. Because the dimples reduce air drag(on golf balls & respectively on vehicles), this creates significant mpg improvements. Combining this with carbon-fiber panels will also decrease weight & further mpg gains.
