Everytime I see the name Aztec, I chuckle and shakes my head. I think someone on the design team got infatuated with all the military stealth stuff and wanted to design a car that looked just as angular.
When you watch Pontiac commercials, look at their sales mark - We build driving excitement. All of their commercials tout the performance aspect of their products and are aimed at daily drivers who want a little "excitement" in the daily commute in the form of a little more horsepower and handling. Not all of their products are considered high performance vehicles, however GM markets Pontiac products as high(er) performance.
Having said that, I will not defend the Aztec or Vibe. I still get a chuckle at seeing the occasional Aztec on the road.
