I don't know anything about these two but I'm in the market for a small 4-cylinder sedan. I have a 72 Chevelle and a 87 Silverado 4x4 and they get about 10 mpg. The truck will be paid off in a couple months and I think it's time to buy something that gets 30 mpg, has A/C, and that I don't have to work on. Cavaliers aren't comfortable to me. Honda Civics are great, but I'm exploring all my options. I don't care what Ford or Dodge have. The Cobalts and the Mazda 3s are new to me though and I really like the looks of both. Anybody have one? What's the good and bad? I'm gonna try to pick up a new car shopper kinda mag tomorrow and do some test drives this weekend.
