I bought a used '08 in Florida last week and drove it home 1000 miles to DC. I'm quite surprised after doing the math that it was getting over 32 mpg for the whole trip. And that was with the cruise on 75 mph most of the way and the A/C on half the time. Can't help to think what it would get at 55 mph. Thats probably as good as a smaller Malibu or even Cobalt. Anyone else getting such high mileage?
