Each quarter panel comes off easily. Fold the seats forward and out of the way. Then unclip the safety belt plug. There is one on each side under the seats. Remove the rear foot/scuff protector piece. Then take off the rear pillar cover - the one between the panel and the head liner. Then grab a quarter panel and pull outward. They each pop right off. When you go to put them back reverse the order and just re-align the rubber stripping and the rear floor plastic shield.
