I'm interested to see how aluminum will affect resale. As long as Ford engineers can minimize galvanic corrosion, the body should remain in good shape minus any dents and dings it picks up. My point is you won't have a rusted through body in 5-10 years up in the rust belt like you get now with all brands. I've got an aluminum fishing boat that is over 60 years old, that has spent much of it's life sitting outside and has held up very nicely considering all the rocks it's bumped up against and been dragged over getting it in and out of the water (rarely use a boat ramp.) There is some oxidation but considering it is bare metal, that is to be expected, and aluminum oxidation is nothing compared to steel rusting.
