You know, I never thought I'd "like" the sound of a four cylinder engine (spoiled by our Duratec engines of course). I've found that if you just keep the exhaust "quiet" as stock on those cars, it still sounds great. It must be me. :shrugs:
I sat in a cobalt at the Buffalo auto show a year or two back. I liked it quite a bit. My buddy owns a black two door Cobalt, and it's a nice reliable car.
Good choice imo
