I think they might go a bit lower but it depends on the particular dealer. I sold our 2016 Sport last spring because my local AS dealer offered us such a lowball trade-in on a Pendleton. They weren't interested in making a deal and were convinced that if I went out of state (which only took a few phone calls to find a better deal) for a better price they'd still sell the Pendleton and not have lost a sale. Bonehead thinking...
Make an offer of 42K, and be prepared to act if they bite.
Don't look back, you're not headed there anyway
