I still have a NIB body kit for the Clod Buster, the first one with the chevy emblem in the grill.
An Optima Mid Special (I think that was the name) - came stock with the carbon chassis. Mint, never run.
My almost mint all stock Avante. Bought it new, ran it once or twice, and shelved it.
And apparently an almost unpainted King Cab body. Tried painting the tail lights, didn't like it, so bought an aftermarket stadium body and used that instead. Still have it and the King Cab, but never run it anymore.
