In my eyes the biggest problem with the Pontiac brand is that it's nearly impossible to tell a $45,000 Pontiac from a $20,000 Pontiac. All their cars look too much alike. I think this carries over from the 80's when a Pontiac was just a Chevy with some plastic cladding around the lower part of the body.
Cadillac's models also look too much alike, even though I really don't care for the "angular" styling they are currently doing.
At least my Crossfire
LOOKS like it costs more than a Sebring.
