I haven't researched into the cars much because of the everyday discussions about their woes, and went into researching the Z. You seem a lot more knowledgeable about the Porsches than I and I trust your word, but their stories made the decision easy for me added into the varying years of cars and still having issues across the board. The choice from then came down to the Nissan or the BMW for me and the Z won based on personal taste.

I don't own a Z (yet), and have never owned a Porsche or a BMW. I do own a C300 Sport and a Civic but those are different creatures. My opinion is only conjecture based on anecdotes.
