I don't ever feel guilty driving my car. It gets 35 mpg on the highway which is high by American standards. It costs about 40 dollars a week to fill up. Of course with all of the savings comes a hefty price in driving enjoyment. It handles like a bathtub, the ride is rough and it gets tossed around by anything bigger than a Honda CRV. It's a Saturn btw, GM can kiss my a**.
