I dunno, perhaps you're right, especially in regards to the selling it at a premium thing. Those different front ends, lights, badging, steering wheels with different Logo's, etc. might seem cheap, but when produced in mass quantities will cost major $$. I didn't factor in the fact that they do sell GMC's at a premium, so perhaps it ends up working in their favor. I'd be curious to know how the numbers really look on their end....

As well, don't forget, just keeping the GMC name running, promo'ing it, adverts, GMC specific Dealers, etc. all cost money too.
