i meant to post this a couple of weeks ago. someone may have already in the past.
when you open the doors, both sides, and look below the bottom hinge, there is an area at the bottom of the front quarter panel that collects leaves and dirt and crap. this is usually wet, and if left there for a long time, would cause cancerous rust. when i looked there over christmas, there was a bunch of wet leaves and wet dirt there. i used a large set of tweezers and an air hose to blow/clean it out.
