This is a little different in that Z06 is the name of a package on the Corvette, not the name of the actual car like A4/S4 is. I don't think they' trying to fool anyone into thinking that Z07 a legitimate Chevy option. It's just supposed to be funny. Like when one of the vintage Mustang parts suppliers made a GT351 package consisting of a 351 Windsor and lots of replica Shelby parts, they didn't expect people to think they were real Shelbys. Or the 502SS kit made for the Chevy 454SS trucks.

Lighten up. Damn.
