The folks at the Dodge dealer and the corp have told me that the corrosion on the exhaust and mounts on the under body are normal. Normal corrosion after 4000 miles? Has anyone else looked under their ride and seen "normal corrosion?" The vechicle I traded had less "normal corrosion." They (the corp.) refuse to address the problem. Of course they already have my money. Does anyone wanna buy my Nitro?
