Do I "hate" Chevy? Absolutely NOT! I'm proud of what Chevrolet represents, and IS. And the vehicles that wear that name will forever be remembered.
However, many years ago Chevy was completely independant in terms of powertrains and vehicles....but not anymore. It'd be delusional to ignore the "GM" side of things when talking about product.
For example: GM decided to build and produce the ZL1. The Camaro team (Chevy), designed and engineered it (which is most of the work)...but ultimately, it was the directors and top management of the corporation that gave the car a green-light.
And when advanced technologies are developed, like the dual-mode hybrid system, or the LS-series of engines...they're used across most (if not all) brands, so I just refer to "GM" when talking about those.
(I also think it's kinda cool to talk about "The General".....
