I have a friend that is interested in getting a preowned boxster and he has asked me to help find him one. I've never owned a boxster and although I have experience with the 911 I don't feel nearly as knowledgeable on the 986 and need some assistance in avoiding potential problems. Are there any model years that should be avoided, or better than others. From what I can tell a preowned 2001-2003 is in his price range.Thanks in advance for your help.
