The Minivan Problem

Okay all you other moms, stay at home or not, please back me up on this...no matter how hard I try my minivan stays messy! My husband thinks that it stays messy because I don't care! It seems that no matter how hard I try I can't convince him otherwise. But, this stay at home mom thinks it impossible to keep my van clean! I mean I live in that thing some days....you know? I love trying to find ways to keep it organized and clean, but no matter how hard I try I can't succeed. Anyone else have this problem? Or is it just me?
