I would make them a counter offer of what you are prepared to pay. When the car is handed back they just get an auction company to come and pick it up, check for damage (fair wear and tear policy) then put through the auction. My works lease company wanted £8700 for my old car (invoice was £18k OTR, not the 24K list) but got £5400 at auction. Knowing that now, I would make an offer of trade price - pointing out they now have no disposal costs.

Just my opinion, YMMV.
