Not sure if I have the SLE or SLT. I rated the gas milage poor because it is extremely inconsistant. I travel 6 hrs interstate/highway time per week and I go the same speed every time. Some trips I go through a little over a 1/4 and sometimes I go through a whole tank. Thats a huge difference! Also, it should get better milage than a truck 17mpg just doesn't cut it for its size. I rated the interior design poorly also because there is only one cup holder, back seats don't really fold down, console is tiny, and the computer system randomly turns on and off the change oil light. As far as build quality stuff I had to have the powertrain completely replaced when I first bought it.
Comfortable and easy to manuever
Put in more than one cup holder so the passenger has a place to put their drink. Also, improve gas milage/consistantcy.
