I am not sure if some people get lemons, but we are on our 3rd Aveo and have never had a significant problem. I have had both LS and LT models. I now have an automatic LT sedan and average 30 mpg's combined city/highway on a regular basis. I drive normally most of the time but I suspect some people who complain about MPG's just really drive their cars way too hard. I get excellent deals from my dealer and commute 60 miles a day making this car a real money saver. Due to the lower cost of the car I spend much less overall on this car than my friends who but imports in the same class.
