The catalog files this silver-and-green example under 2008 and explicitly warns that it may not have been released. It provides no toy code. Treat 2008 as the catalog’s reference year, not proof that the car reached shops.

Prototype and documented retail versions





Choosing one for your collection
Ask for the history of the specific example, including any records supporting its factory origin. A repaint can resemble a reference photograph without sharing its provenance.
The catalog calls this a prototype or factory test shot. Retail release, toy code and production quantity are not established by the available reference.
Collector questions
Can this photo authenticate a silver-and-green car offered for sale?
No. A matching color scheme alone does not establish factory origin. An example described as a prototype needs its own provenance; this photo does not confirm a retail release or authenticate another car.
