Inexplicably, the Type 3 Notchback was never officially sold here; VW of America didn't think it would sell. That didn't stop some Americans from importing a few through the "gray market," which is probably how that blue Sharan I saw in Manhattan got here.VWoA still needed a family car to supplement the Beetles, and it finally brought over the Type 3 Fastback, a picture of which I already posted.
But you're right; the Jetta isn't the first car to be created from an existing Volkswagen. In fact, there was a new Beetle model created from the existing Beetle. . .
