My most recent issue of Pop. Mech. says that in 2015 the F-150 will be 700 lbs lighter with an all aluminum body. It will have more cargo capacity, better gas mileage, and higher insurance because not many body shops have tools to straighten dented aluminum. The F-150 is Ford's bread and butter, and they sell more than any other vehicle. If sales are good they say other major manufacturers will follow to meet federal gas consumption standards. Maybe Alcoa Aluminum stock will go up in the next five to ten years if Ford and the others buy aluminum from an American company. I think China then Russia have the most aluminum in the world. I think Alcoa is about eleven dollars a share. If I had money or even a portfolio I would think about buying a thousand shares. I don't think it would go down or lose money. You never know the future though.
