I owned a cobalt SS SUPERCHARGED with a few mods. But after buying the acura rsx, ill never go back to driving the cobalt. First off the interior feels cheap, everything is plastic and basic, and shitty leather seats. second i had lots of mechanical issues with mine it sometimes ran lean, sometimes rich, bad o2 sensors. Also gas milage was terrible. Now the good, tons of power with just a stage 2 kit, intake, exhaust, and a tune. The supercharger screams under wide open throttle. Handling was good too. Overall i was not too happy with the car.
