I had low expectations for this car because I only bought it for the mpg (which became much higher after adding in an aem cai and an 2.25" cat-back) it was much faster after a few upgrades. I was able to keep up with Civic si's (both 2dr & 4dr) & some times beat them if I can keep the tires from spinning from a dig. Got to love that torque which is lacking & higher stock cobalt ls vs. Stock Civic si. But had to upgrade clutch after first year :-d. Anyways it's a great tuner car just wish the market would embrace the mighty cobalt which gm already helped with there ecotec recipe book look it up trust me you'll want one to after reading through the stage upgrades 4 gm doing the R&D for you already
torque, mpg (35-40 hwy/25-30 city), sleeper status, great rear-end ;-) i love a good rear-end if you know what i mean, good drive-train, good balance once stiffen up a bit & predictable while on track if setup correctly
some touch points, interior, wheels, lsd should be standard, more hp/tq & mpg+(but never could have enough :-D), maybe add in some boost stock, more tuned chassis, stiffer around corners & power everything standard.
