This is a great find! Its the Chevrolet Corvair Concept Car from the Johnny Lightning, The Fabulous Motorama series.

It's a hard to find piece for several reasons: First, they only made the  Motorama series for one release which was 20+ years ago in 2002. There are only a handful of variations of this casting, the only 1:64 casting of this car from any mfg we are aware of. This concept eventually became the Corvette.

If you collect Concepts, Chevy, Corvair or Johnny Lightning this is a wonderful addition for your collection (1:64 Scale)
