Whoa, that's actually pretty cool. I am not too into auto mechanics myself, but I understand enough to where I know how vehicles work and how they're made. I'm surprised how thick a lot of the parts for older cars compared to ones nowadays in general. But then, there's also a lot more electrical crap in them too, which is harder to work around than 1990s vehicles. I can imagine future vehicles being made from even lighter material, but if you can strengthen their integrity too, that'd be surely awesome.
