Bone simple response to all of this: If you like it, buy it, if not, dont.
Now to elaborate. This car will be quite fast. This we know. The Saturn is starting at a disadvantage because of the packaging (the goofy dash, et al).
The Cobalt SS has good power, and should handle decently enough. There might be some aftermarket goodies available too, because it will be worth tuning. If the seats aren't as crappy as they look, it should be workable.
Add int he fact that it's the lower model Chevy and it should depreciate "like a rock"......As I keep saying, depreciation is our friend.
