The two dealers I do buisiness with in Central Wisconsin use a blue book called “ABOS.”I think NADA is used mostly by insurance companies and bankers, but dont know that for sure. I tried pricing out my boat there and some of the options are unclear. For instance, I couldnt find an option for a manual jack plate, so picked something that seemed close and NADA said it was worth $1350, so obviously that wasnt right.I think a dealers blue book such as ABOS is a much better source of actual selling prices, since the guys who sell the most boats are using it.Its a subscription service of course, but if you have a dealer you regularly do business with, he should help you price any boat youre selling. Both of “my” dealers have done this for me.The Basscat I am selling, boat/motor/trailer comes out to $17, 640 in ABOS (not including accessories). I couldnt get a valid price using NADA, but admit I didnt try very hard.
