Some of the coolest sports cars ever to grace the great American road have been, well, Japanese. Yet so many have suffered the ignominy of cancellation or been dismissed as bland and inferior. Blessed few have managed a revival: the Toyota AE86 lives today as the GT86, aka the Scion FR-S, and the NSX's return was many years in the making. These are 16 of the very best that, for various reasons, died and haven't (yet!) achieved resurrection. If the car gods are smiling, perhaps a couple of these will see the light of day in the coming years.
