I did a quick search on NADA, but since I have no idea what the options are, I just clicked past it, so the one you are looking at may be worth more.:)
Not knowing what you have now, makes it difficult to give you an honest answer....if you've got a $25K "C" and are upgrading, this would be a pretty good deal:).....if you've got a $100K coach, not so much:(
(edit, I see you mentioned your Winnie, but not the year>)
HERE is what I got from NADA.
You may want to go there, and compare the prices with what you have, and what options you are getting....at least then, you could make a pretty fair judgement.
Good Luck:)
