(PPI- Pre Purchase Information)

I need some advice from you guys. I am actually looking into getting a boxster and found one I like. Its a 2002 boxster with 43000 miles on it. Is there anything I should be aware of for this years model? factory recalls leaking seals etc etc.... whatever you can think of
What would you expect to pay for it?
I will post pictures right after I have been looking at the car
Thanks for your help
