The car manufacturers have always dissapeared - that's not so big drama, the main problem of our times is the fact, that since many years it is completly not possible to create any new car producer in Europe, mainly because of the "free market" and big international concerns, which are competitors not to defeating in such shape.
So, yes - that's true - existance of smaller manufacturers is impossible in today's politic and economic order, but nothing lasts forever... I like to be optimistic.
