Our city mileage isn't too bad at all. Granted, we do about 75% city, so there is some highway mixed in there, but generally the longest stretch is only about 10 miles. And a lot of the city is stop and go.Only thing I don't like is the city mpg. I got the same city mpg from my 2005 cobalt.
It's a new vehicle so there's going to be some kinks to work out like any new product. If you didn't have the patience to deal with the bad hand you were given then that's fine. Most of the people, including myself, are very happy with the CTD and have thoroughly enjoyed it.
