What am I missing? S vs. R
 

I was comparing the S to the R on Porsche's web site and it appears the R is a little cheaper for comparably equipped cars.

It looks like you have to add the Aero Kit, Side Strip, Sports Bucket Seats, Climate Control and LSD to the S and A/C (which includes Climate Control) to the R.

However, I am not sure that is totally correct. If it is, the R is almost $5,000 less than the S. Am I missing something?
