I have basically stripped my aveo, the only thing I haven't taken out yet is the dash. the door panels, seats, front pillars, center console, center pillars for the front seat belts and all the lower panels are all easy to remove. the rear pillars with the quarter panel windows, that is where it can be a pain with the retaining clips. its been a while since i have stripped the car down doing audio, but if i remember correctly you have to pull a couple clips then slide the pillar towards the front of the car to remove it. after that you can remove hand grips then the headliner and carpet.
