According to GM Authority, the company sent a letter to dealers that limited orders on 35 individual parts that make up the Z/28 package. The list included a mix of mechanical and aesthetic components like the brakes, wheels, differential, body flares, seats, grille and even the emblems.
This is clearly a move by Chevy to protect the exclusivity of the Z/28. As you can understand, it would harm the hardcore car's reputation if a replica could be built easily from a much more basic Camaro powered by a V6. In any case, for the time being, it also means that interested buyers must negotiate for the few remaining 2014 models left, or they have to wait for the 2015s to arrive.
