I have a buddy who passed away recently and his father has come to me for advice. He has a 2003 XP-DI with out 35-45hrs on it he wants to sell. I have checked NADA and they say about 5700-6400. The ski comes with a trailer and cover. It is a really clean ski. If anyone has any advice on a good price or what you might have seen them selling for I would greatly appreciate hearing it.
