I loved my cobalt when I first got it; it was fun and easy to drive. After the first year or so, a lot started going wrong, however. In the past 2 years I've had to have 2 door handle replacements, the sunroof has gone offtrack twice, & in the past 4 months alone I've had to fix a leak coming from within the hood of the car (they had to remove the passenger seats & headlights to figure out where it was coming from -- cost about $500 to fix), 2 tired replacements (wear very easily), had an alignment, and got a new battery because it went completely dead. Also the cruise control decides when it wants to work.
Great gas mileage!
If more time and money was spent on making this car it would be perfect, but it is just too unreliable.
