Yes - lucky or wise to have checked out the PO as well as the car. I think buying ones Porsche from a fellow fanatic is an excellent idea.
My experiences have been that the person that owned either of the four Porsches I have owned were just the opposite. Don't fix anything you can get away with neglecting. On the other hand this way I have gotten to know my cars very well whether I wanted to or not. In many ways I feel that I am going Porschdom a service by reclaiming them from the heathen!!!
