It would be cool if more and more vehicles moved towards aluminum. however, there is not a lot of expertise out there to fix aluminum vehicles in the event of a crash.
My thoughts are once the insurance industry starts to get a handle, called "experience" for their tables, that initially rates could start to climb as they realize how expensive they will be to fix
on top of that, there will not be a large pool of used parts to pull from so everyone will be getting the new oem parts guarantee
the upside, you won't be fighting rust so bad. sure aluminum corrodes but not as fast as steel rusts, especially here in Ohio. it is a constant and ongoing battle to keep my 2004.5 2500HD free from rust.
