i was just waking up and looked out of my window, i see my car, and i think about all the concept cars that GM made. are there part numbers out there or conversion kits or anything out there for the alero OSV, turbo sport, solstice, or that sunfire autocross. these cars are friggin' awesome, the OSV got brembo brakes and a supercharged 2.4 (230HP) the sunfire autocross got IRS, it just seems like for whatever reason GM flushed these ideas. the cobalt does give a second chance of hope, however. any car that comes with pirellis on the base model has to be something.
