Hello from MI
I'm an owner of a 2007 Cobalt LS. Can't say I like the car, or hate it.
I've had problem after problem with this car since new, dealer won't ever fix it, and it has an extended warranty. So recently just been repairing everything myself and saying screw the stealership.
Car has 58,000 Miles on it, and is in need of a 4th intermediate steering shaft. Struts are blown out also, but I just picked up some FE5 struts on CSS.net, going to throw some SSC/CM springs on it just to make the car handle a bit better.
I have built a cavalier in my free time that run's mid 13's, probably could get a low 13 if I could ever get the car to launch and hook properly.
Anyways, just here for more info and hopefully get into the classifieds eventually.
