Yeah, those Boxster drivers seem to have something to prove. One time I was driving down PCH in second gear at 4000 rpms (beautiful sound) and a Boxster driver (next to me) dropped into a lower gear to get his engine reving high. Totally unprovoked!
His car sounded like a washer machine that was about to blow. Not a terrible sound, but not an air cooled sound either. I ignored him.
With that being said, I'm guilty of obnoxiously blasting past 996s or other wasser coolers to let them know how a Porsche should sound.
How dare they even consider doing that to me!
