a Boxster S..

Hi i just registered on the forum because i'm considering purchasing a type S. i currently own a honda s2000 and after three years of abuse at the track, it's about time for me to move on to something else.
i'm considering purchasing a used type S, simply because i purchased my S2000 brand new, and three years later i'm realizing what a mistake it was[sm=headbang.gif] to purchase a brand new car...
so i just wanted some feedback about hte differences between the type S models from about 2001 and on.. i.e. any factory recalls, engine failures (cylinders, pistons, etc...) with track use, etc... any suspension tweaks over the years, stuff like that... any feedback is appreciated, thanks!
