Honest question: aside from the outside looks, what's so bad about this vehicle? (I started driving in the year 2006 so Aztek has been off market for sometime.)
It looks cheap. Its front is a single molded piece of cheap plastic that goes from the undercarriage to the hood. It is surrounded on all sides by more cheap looking plastic bits. GM is infamous for putting cheap plastic bits on their cars that simply don't stand up to the elements; so anyone who has ever owned a GM car knows what an Aztek is going to look like after the warranty period is over. As it turns out GM must have improved thier plastics and the Aztek has aged well. But there was no way to look at one when it was new and tell that it wouldn't crumble like an old milk jug after six or eight years in the sun.
