GMC Sierra HD
No big surprises here. Anything you can order on the Chevy you can get from GMC as well, except now there's more visual distinction. Long the red-headed stepchild, GMC is beginning to carve out its own territory away from Chevy. First it was the premium-trim Denali brand, making its way onto pickup trucks and SUVs, and now the Acadia crossover is turning heads and opening GMC up to an entirely new market segment. Don't be surprised if GMC has a few more trick trucks up its sleeve. With all the play in the luxury-truck market, how far away can the Crew Cab Sierra 3500 Denali option package be? Certainly Cadillac can't play there, but GMC can. A few exclusive accessories, some plush carpeting, and a large-screen DVD player and Bose system--we'd tow our boat to the river in one of those. More to come, we're sure.--M.W.
