I'm a Ford guy, but in my years of the auto repair business, the only thing I found aluminum good for was beer cans! If they have found a way for aluminum not to corrode, then maybe. Aluminum wheels corrode after a few years and then you either demount the tires, clean wheels and reseal or put air in every week. Aluminum blocks, heads, radiators, are all junk IMO.
Thanks for replies so far all.
Topstock, this is the issue I was trying to address mostly. A long time mechanic fiend of mine said the same. He mentioned that at one time Ford used an aluminum backer plate on the rear bumper, and they had issues with that. Kind of hate buying any vehicle the first year they make major changes to things.
