I got my vert from the dealer before it was finished being prepared so I could send it for a supercharger and they left all the papers inside. So I found about 20 tags that get hung in the car for quality control. After I saw all those tags I realized that they have sent each car through rigorous testing and checking before being sent out. I mean lots of tags!
So while I was pissed at having to wait so long I now know why. GM should have a better info system to say " gone through quality control check 3 of 145!"
