It will be interesting to see where the independent mechanic is in the next 50 years or so, the technology for the cars is changing rapidly and they are more and more software as much as hardware.
I did speak to a family member about Porsche and basically the minnow "Porsche" got way ahead of itself on 2007 when it made a stock grab for the largest auto company in the world, VW. When the crash came in 2008 it was bad timing and Porsche was so backwards in debt from the loans it took to buy VW stock that VW eventually came in and rescued Porsche.
Its really too bad, but that's what happens when greed and power go to your head. I wouldn't be surpised if Porsche eventually goes back to being and independed manufacturer.
