Lots of rose colored glasses being worn here.

I will take modern rust prevention tech every day all day. The control modules and circuit boards are a hole in repairablity, and there'll be a wall where nobody makes them anymore and the specs are not published (considered proprietary/trade secret/whatever), and that whole vehicle will just have to be scrapped. The world won't ever see the end of old body-on-frame vehicles with crate engines. Speaking for myself the "rose colored glasses" is a wish for the best of both worlds. I wouldn't doubt it's out there being done somewhere, but I'm sure it's cost prohibitive to do it, or people are doing it for themselves.

Maybe I'm just complaining because I don't personally have the time/knowledge/workspace to do what I want in that area. C’est la vie.
