I think what he meant was not so much directed at the Z/28 purists, but an outside buyer who has the expendable income. They might look at the Z/28 then see they can get a corvette nicely equipped for less. I think that is where he was coming from.
This statement will probably piss of some of the people here, but I think he was trying to find a nice way to say "its still just a camaro and some people will have a hard time spending that much on a camaro but would rather spend it on a Corvette " haha. That's what group I would be in. At a certain price point I would rather get into a Corvette
