Many thanks to MCCH member Mr. Lobo (his friends know him as Jorge) for pointing this new variation out. After he let me know, I went out looking for it, and sure enough I found it.
The Hot Wheels Mystery Batch B COPO Camaro has already provided a few variations, none stranger than the blue stripe vari we reported yesterday.
