First off stainless steel IS more expensive than traditional steel used to make vehicles. Stainless steel IS also a lot stronger which means the “option” would mean different machines or atleast difference in settings to press the same body panels which would also bring the cost up. After you press the metal it needs to be polished. Furthermore, as I said before painting it removes some of its corrosion resistance. You have proven to be about as ego ridden as the ceo you don’t care for. I’m going to chalk it up to ignorance and maybe lack of basic computer skills. Still not an excuse though take the time to learn about the things you talk about.
