Some SUV's aren't too bad. SOmething you would definatley look at before purchasing, though. My Durango got 23 mpg on our trip to the beach, and that was with sitting in traffic for over an hour....but, normally, it was doing better and better. It was getting around 18-20 at the end...(which I know isn't the best, no where near what your Saturn gets, I'm sure.)
I have a 1974 VW super beetle in the garage...they get around 40!
