i just a g6 on last thursaday stock model nothing fancy but i did get the windows tinted ,but something ****ing already went wrong in the front right tire area (virbration or something )but i got a warranty until 2009 so looks like ill be using that b#@h!
lmao... the vibrations would eventually go away even if you didnt get them balanced/ rotated. Sounds to me like the car you bought had been sitting in the same place on that car lot for a while. That would make the tire slightly deform from sitting in 1 spot, nothing major at all. I know Im late responding but just thought you should know what the problem most likely was.
