I traded in my gas guzzler after gas topped $3 a gallon. I needed a car that averaged atleast mid 20's to a gallon. After some serching and not wanting a 4 door the cobalt was my choice. I got the LT version for 18,000 including taxes. So far the car has performed well, but did have a paint peeling issue on the front bumper, which they repaired. There is nothing to jump up and down for on this car, it's transportation. It's basic wheels.
Better visability. You really have a hard time seeing out the rear window. Bad design I didn't realize till after the fact.
