I wasn't sure if this was a common thing or not. I never knew my '86 did, but one day I followed it in another car and noticed I could see the drivers side as it was driving straight. Also, if anyone has ever seen the video of a green 81-83 (converted to manual trans) that goes down the dragstrip it also favors one side. Were these cars just set up that way or is there a problem somewhere? I never noticed a Cutlass or Monte Carlo doing this.
