Without the SUVs Porsche would have been history. 

I would say this is not true.

There would have been other ways to safe the company. The moment the SUVs been planned Porsche already was kind of financially stable. The problem was that the egocentric CEO tried to become the highest paid and most powerful automotive manager of the world.

1st - Porsche could have stayed small and financially stable. Growth would have been much smaller but the spirit might have been survived

2nd - Porsche could have actively gave up its independence - meaning, instead of planning an unfriendly take over of VW they could have actively managed to go underneath VW

Either way would have made Porsche surviving, too. 

Nevertheless: Out of shareholder view everything went right. The share went sky rocket, the company grows and grows. Again.... they build cars to make shareholders and their own pockets happy. It is not because the spirit of building fine cars.

And btw.... have a look at Ferrari or at Lamborghini. Both managed to stay supercar builders in more or less a mixture of the above mentioned 1./2. steps.
