I have noted that most of the first Gen cars that I've seen have large cracks, holes or even missing inner fender liners. I already replaced both of mine and I'd rather replace the intake manifold any day than a fender liner.
I haven't noticed if this is also common on the Matrix and Corolla. I wonder if these poor fender liners are common across the entire line or do the Vibes use different ones than what is used on the Matrix?
