Audi, Jaguar and BMW will be the first big victims of the sudden increase in aluminum construction in their cars. I was surprised to see MB hasn't jumped into using aluminum as much as those automakers have used on some of their cars - good idea, as MB has gotten too much bad rap lately on bringing new features not yet thoroughly tested to the market. A structural flaw in such an expensive vehicle would be a huge embarassment for the automaker. Much bigger than electronic issues.
