The Monza Scorpion is a very rare entity that has only made its appearance recently and with only a few limited examples, little information about this edition is known. It is not a GM installed factory option package but more likely an individual Chevrolet dealer issued and installed package to help generate sales. For the most part, it is simply a decal package, nothing more, and no 2 Scorpion packages seem to be alike, so far. Essentially the package consists of a hood decal and side stripes of some type to make the Scorpion appearance package. Still waiting, and hoping, for someone to find a build sheet or a dealership the car was sold from in order to get some more info on this rare Special Edition.
The two Scorpions (left margin) were both on ebay a few years ago now.
