I don't think you'd have a problem selling your Class C on your own or put it on consignment which we did and it sold within a month.
You won't be getting anything on a trade and your best price will be without a trade. Test it. Go to a dealer and ask how much w/o a trade. Get the price and then ask what about with a trade? Don't give him any indication of trading at first. Then you'll know how much your trade will be and come armed with what you think it's worth so you know if the trade price is good or not.
