Hi I am looking to buy a pair of personal watercraft, but don't know much about them at this point. I am thinking about buying a 1997 GSX and a 1996 GTI Sea Doo for $4000. First I was wondering if this is a fair price for these two. My second question is are these fairly dependable or are they likely to have problems. My final question do personal watercraft in general take a lot of tinkering to keep in good running order other than general maintenance. Thanks for your help.
