this mauy be a little late but the G8 and G6 are supossed to be the generations of the cars G8, 8th generation of the Grand Prix, G6 6th generation of the Grand Am, I don't understand why they kept GMC when all GMC is is a rebaged Chevy Truck, Buick is doing very well in China, Chevy is the may stake for GM but Pontiac sales we double that of Chev for the 2008 year, G8 was an exciting car....or is an exciting car! Pontiacs last muscle car!!!!
RIP Pontiac!
