I have a question I need to pose. I am considering upgrading to the performance. However, I wouldn't get either the carbon fiber interior or the performance rims - just not my color tastes. I don't really care about the exterior accents. Plus it would force me to go to the black interior from white - I can't have white alcantara with two kids, they will destroy that in a week. SO that leaves the question - is going from a 60 time of 5.6 to 4.4 really worth $10k? Is 5.6 "fast enough?"
