Mr. Ciferri is absolutely right in his analyses. There just isn't such thing as the need for low volume plants, the others would not have closed lately. Car manufacturers were previously not organised to combine more than a couple of different models in one plant, today they are. Premium makes as Mercedes Benz and BMW have in access of 20 different models counting for just over 1M cars a year. Things have changed and Belgian circumstances aren't at best to face the competition from countries close by and far away.
It lacks the courage to close and start with something new, notoriously politics neither help to extent the view.
