New 1968 model, available today
Part of the appeal is the price: about $9,500. And I think the appeal to Nissan is using the molding for that model without having to scrap it. And to be honest, it's a basic vehicle and must be easier to work on compared to more modern vehicles. But this could be another case of the developing world getting the cast-offs from the rest of the world.
I just noticed the ad's headline; it could be interpreted, "This Nissan Model will be Sold Forever!"
