Really?? I have an 07 hatch and i pull a coleman 4x8 fold-up trailer all the time, recently went 445 miles with a full load (1325lbs at the scales-glad they were closed) it also works great for my bike rack, also tow an occasional jet-ski or my motorcyle on same trailer, jetski has its own of course..
We ran 75 on the flats and of course pulled down to 45-55 in the hills.
And still got 28mpg so dont under-estimate your aveo.. Lovin mine!!
