IMO - and I can definitely appreciate the irony in me saying this, as well as the overwhelming uproar that it's going to generate - Pontiac, Buick, and GMC are all superfluous models at this point. They don't have anything to offer the American buyer that isn't badge engineered.
The Solstice seems to be moderately successful. IMO, GM should drop Buick, GMC, and all but Pontiac's performance-driven models (i.e. GTO, Solstice) like a bad habit. We don't need a Pontiac minivan that's identical to Chevy's. We don't need a Pontiac SUV that's identical to Chevy's. So on and so forth.
Pontiac hasn't got a very favorable image in the public's eye; to offer up rehashed designs and models only serves to further the media's contention that it's a throw-away brand.
Kudos to Lutz for losing the plastic cladding, grills, gills, and wings - but he shouldn't stop there.
