There's always economy of scale. Steel is cheap because of the massive scale in which it's produced. Last I checked (A long long time ago), the US is the world's top manufacturer of Aluminum. Maybe we'd see more mines start up to sell the material? Then as repairs become more common-place, they'd get cheaper. How much cheaper? I have no idea, but I'm sure there's something to be gained with economies of scale. Interesting statement by Ford though that they're concentrating their aluminum efforts only on the pickups, leaving the cars steel for now. Maybe there just isn't as much opportunity with cars given the advances of AHSS.
