I think this would be a great idea; I don't think it will happen though

I don't see why GM would start that again, after all this time, although I'd love them to.
For me, I want the biggest/most powerful engine, manual, power, hardtop, best chassis setup (brakes, springs, shocks, etc.,) leather, good stereo, no navigation, and as many OEM performance parts as I can. Hopefully, with a FI'd engine (assuming that would be an option) I'd add a pulley, CAI, catback, smog legal headers, a custom tune, and maybe some accessory body components.
