Spoiler Prototypes 
Shown below are Spoiler prototypes. These may also be called pre-production samples or test shots. Meaning, the Johnny Lightning designers receive no more than five of a casting from the factory to check on fit, finish and wheel type for example. This is the time where the designers make corrections and/or adjustments. Sometimes these cars make it into production, and sometimes they don't.

None of the cars pictured belong to me. The pics were sent anonymously.
