Keep them clean, dry inside so they smell new when you go to sell them, don't try to make money but just break even and if there is a problem later on hook them up with the right people to get it taken care of as they will come back if treated right. Don't take them to sites that treat the boat rough. I'm on my 24th CC and have only sold 5 in state. When someone starts the conversation by telling you they are interested but point out what they don't like end it quickly. Set the price fair and don't negotiate......People think Promo's get awesome deals but that is not the case. You are first to a tourney and last to leave and the following day is cleaning the boat.
