    dammit, I have to try to beat your highway!!! My car was full of stuff too. I'll try to see what it does with only me. Slim chance of me driving ~800 miles to find out without some extra clothes and stuff. lol

    Its not that we buy these cars for the gas mileage, its just nice that they get better than 10mpg!
    For the money, there is no car available that will give you the kind of performance in acceleration, handling, and drivability that an f-body will.
