Chevrolet is as American as Apple Pie. You're making far too many assumptions, and not giving enough credit where it's due.:( Look up domestic parts content for car brands (you'd be surprised)...realize that there shouldn't be any ill-will between the US and Canada (the Camaro's been built there for over a decade, if not two)...
ALL of GM-brand dealers are ranked among the best in the nation in terms of sales satisfaction. And believe it or not, Toyota ranks BELOW average (which is already a pretty low bar):

And you're making wild assumptions about the company's handling of the Camaro. We...as a community....are extremely nosey. We see and hear things that should never be seen or heard. All in all, with a few road bumps, the Camaro's concept to production journey has been pretty smooth sailing.
