You should go to Corbins web site and price out that seat so you have an idea what it would sell for new because if the Dealer is smart that's what he will do. Then you can work from there. I would guess as long as the Dealer can make money on the deal he will go for it but he has to turn a profit or it is not worth doing.

Now that being said, for an example,,,, I sold my Corbin with backrest last year for around $600.
