Disclaimer: In no way is this meant to be any sort of official preview of the 6th gen. Just something that was noticed. More than likely GM had to approve this photo before it was published and made sure nothing in the background was of any value future product wise whatsoever.
Again, because I know what some of you are thinking.
THIS IS MORE THAN LIKELY NOT THE 6TH GEN.
Coupe on the design wall by Barra's leg. Interesting design.
