This has been a great car! I have put 26000 miles on it, all trouble free. Went to the dealer one time for warranty work, just a stuck ecv valve, total time at the dealership was less than 1/2 hour. Gas mileage is great, better than the EPA estimates. It would be hard to find a better car for the money. While the Cobalt is the replacement for the Cavalier, the Cobalt has nothing in common with it's predecessor. Everything about the Cobalt is leaps and bounds above the Cavalier.
Ride quality is great. Road noise is minimal, this is a very quiet car. Power is decent.
Ditch the light gray interior. It shows dirt really bad. If you have kids, opt for the 4 door, as I have a 2 door and 2 kids and the back seat is tight. Pay the $80 for the center console armrest, you'll be glad you did.
