Following the Obama administration's decision to assist and allow American-based automakers to "clean up their act,” it became apparent, while focusing on trucks and SUVs, that the American sedan was being de-emphasized as U.S. automakers quickly reduced their product lines.
I find GM's decision unfortunate but not surprising. From a personal perspective, though, my first purchase was a 1967 Ford Mustang 2+2 with a 390 V8 (a true muscle car), and every subsequent purchase involved sedans produced by Asian automakers, specifically Japan and then, South Korea.
The reason was simple. I have long believed Asian automakers just design better sedans than their American counterparts.
