I agree from a structure standpoint, but why do we need a X and Y and Z version of G6 even if it is only the badge? And you that would never stand for long and we are back to make n version of body and interior parts for each brand again.
I hate to say it, but I think Saturn has more recognition and loyalty than Pontiac at this point.
Having a GM dealership with 6 brands is still too many. 3 or 4 is probably more reasonable with no model overlap. Toyota who is taking over in market share has what, 2 brands? Nissan = 2, Honda = 2 as well.
I know we love those old monikers, but times have changed. both the business and brands shoudl as well.
