1990 Buick LeSabre Aero Help!
 

Greetings from Michigan.

I recently bought a 1990 Buick LeSabre Sedan and am now anxiously looking for some aerodynamic tips to help make the car into a better commuter car. Currently it gets around 16 mpg in city and it is driven back and forth to college which is roughly 11 miles round trip.

The car is presently stock but i am currently looking into the wheel discs which i suppose would be better than the fake wire wheel covers it has currently. Any tips and advice would be greatly appreciated.
