I just saw an interesting post over PPBB (http://www.ppbb.com/scgi-bin/boards/986/main.pl?read=960094) where someone that tested both the base and S felt that the base sounded better. A second person that had only drove the base and ordered the S also had the same "feeling" when he picked us his S.

Anyone had any similar experience?

I've downloaded the Boxster sounds from Porsche web site but they have the same mp3 file for both the base and the S. It does sound very good but I don't know which model does the file refers to.
