For most cars, when they've reached the end of their production cycles, they're discontinued, and that's the end of them.
Volkswagen has a different way of doing things, though. When the German automaker replaces a model, the old one is often sent off to other markets to live the remainder of its days. Never mind the Seat Exeo that's essentially an old
Audi A4. Some seriously old VWs have been given stays of execution in far-flung markets, like the original Microbus that's still made in Brazil as the Kombi.
