I have a '07 FWD SEL 120K...I live in Northeast Ohio where the state/ cities put that salt/ brine down in the winter.....I believe that is the culprit to rotting the seam where the two halves meet and around the fuel inlet area....I received a tank from Tx. $256.00 shipping was most of that... no rust at all.....go figure....yes expensive replacement $1500 new tank then installation cost...overall great vehicle....
