This is my first American car in 30 years and none of the frames of my Honda's ever looked like that!!! even beyond 10 years old.
This C-max was originally from Trenton, MI but had only spent one winter in MI then moved South. I live in Atlanta, GA.
And yes, this is considered rusting out. The rust starts on the inside...when you see if visibly it usually has rusted through.
