It's a horrible boat. Don't buy one. By the way, if you find a good deal on one please let me know... ha jk
The Super Sport is probably the most high in-demand older wakeboard boat out there. The GT40 engine was supposedly one of the best produced by nautique. Can't go wrong with CC build quality. I believe the Super Sport has been discontinued for a while.
Haven't heard a lot about the kinks, so I can't help you there...
All around, it's a solid boat with a legendary wake for boarding!
