A few days after purchasing my new GT, I discovered that all the aluminum components under the hood were severely corroded and all the steel parts under the vehicle rusted. The dealer said that they have seen this condition before, apparently some cars got road tested on the salted roads of Michigan and did not get a wash job before being delivered to dealers. Four of the ten new Mustangs on the dealers lot are corroded. My car has become permanently disfigured and devalued. Ford Corporate was notified on 3/1/05 but have yet to provide a written response. Please inspect your car closely and provide the forum some feedback, as I would like to hear how widespread this problem is.
