Yep, could have bought the S, but then my logic:
1.  I need to learn to drive first.  'Slower' cars need better drivers - now I have to learn.  Umm, I have a modified WRX that will out accelerate most Boxsters - S or not.  Fun car, but now too many kids have it.
2.  Blow up my motor, out goes the 2.7, in goes the 3.4  
3.  Yeah, resale for the S is better, but I have a history of giving my used cars to relatives anyway.
4.  Lastly, all I want.  It's a great handling Porsche.  No justification necessary.  
The best after effect of buying the car - when I get overwhelmed at work, I reach for my keys and
