Damn Ferocious, you say some pretty dumb shit.
The reason "older people" own Shelby's, ZL1s, and will own the Hellcat is simple - they can afford it. Your tune would change if you could afford one of these cars. I just got back from a small dyno gathering this morning with Mustang GTs, a '13 Shelby, a few vettes, and other LS-based muscle like GXPs and whatnot. Lots of superchargers, lots of power - and nobody over 40.
Oh, sinking 20 grand into some shitty V6 is retarded, and you'd still get crushed on a road course when the "big V8 car pulls 10 buslengths on you in the straights, and is equally fast in the corners.
