I can "get it" that people move to distrust, first. Did you try googling the site?
*There is no "back story". It's site with wicked good articles, that were incredibly well researched. Research that goes way, WAY beyond what you'd see in typical car-guy sites and articles like you'd read on Hagerty, Motor1, Driven, MotorTrend, etc. etc. What *I* love about this stuff is the deep dive into, which ever topic; the people behind the effort (car, transmission design, whatever the topic). The politics of the era, other pressures and influences that steered a product into failure...or success. It's car-topic articles that you do not typically see or find. That's all the "back story" that there is, here.
*I'm "affiliated with that linked site" insofar as I've read articles on that site. And Liked 'em. Thought other "car-guys" would too. That's the extent of my "affiliation".
*The site....if you actually looked at the thing, is not-for-profit. The guy makes nothing, doing it, unless people donate, which I've never done. There are no adds, no banners, no pop-ups, it's a pretty spartan format, that has content. So "click-bait"? Spammers? Not likely.
The site is exactly what I said it was. I'm new here, but I've been on other GM/car sites for decades; Thirdgen and the Corvette Forum, for example. Google the site, (and google my screen name too, if you wish!) if you're fearful of it. It's just a site. With car-guy stuff in it. I love it. Other's likely would, too.
