Mazda Lease Return Question

So my wife’s lease is up in July. She has a 2016 Mazda CX-5 leased throught Chase. We like the vehicle and would consider buying it. It’s in good shape with very little minor dents/scratches. The residual value comes close to what the RETAIL worth actually is according to KBB. If we decide to buy it out is there any room for negotiating? Does Chase negotiate or is their price “take it or leave it”? I’ve seen some comparable CX-5’s in our area going for about 1k less. Is it possible to negotiate 1-2k off the purchase price?

Thank you all in advance. New to the forum and look forward to contributing!
