If the Pontiac Fiero was killed for its eventual decline, the Aztek never had a chance. Odd when it was introduced as a concept in 1999, the production Aztek didn't change much when it launched in 2001. A new-age SUV built on a minivan platform, the Aztek certainly polarized opinion, what with its strange and disconnected exterior design. Despite a small and remarkably enthusiastic group of owners, the company eventually shut down Aztek in 2005.
