Hi Tduff and welcome to the forum. Your 2009 is a step up from the older models because it it the first year for the V-2 Drive and has the Click N Go Drive insert. Look on the Craigs list in your area and adjust for condition. The Sport might be $100 less than a comparable Revo 13 or Adventure and maybe $200 less than a tandem -- just as a rough gouge. Take good pics, list all the accessories and upgrades and take your best guess. You can lower the price if there is no interest. Spring is a good time to sell! Good luck!
