So I ended up leasing another Nissan. I wasn't really expecting to go that route, but I somehow managed to squeeze a great deal out of the fuckers at the dealership. They've clearly been hurting for sales over the last year so I'm sure that gave me a little bit of an edge. It was a pretty quick in/out process, HOWEVER:
When I got to to the finance desk, they first tried to sell me a warranty which already came standard with a brand new, leased vehicle. I called them out on it and they immediately dropped it and went on to the next subject. The next subject was going over the dealer/lease fees which are mostly unavoidable. I've leased a few vehicles during my life and this is a standard procedure, they show you the charges (which are already a part of your payment) and then you sign off on it. After explaining the charges, this time they asked me "Okay so do you want to pay these up front or roll them into your payment?". I basically said "what the fuck are you trying to do here" and declared that I've never been asked to pay these up front and that the negotiated payment always included this stuff. They came back with some nonsense like "Oh wow, that's crazy. Unfortunately SOMEONE has to pay these fees, so I don't think we'll be complete this transaction if you aren't willing to pay them". I said no problem, thanks and see you later. Sure enough, it was my "lucky day" and they completely waived the $2400 charge.
About a week later, I got my liability statement for the older lease which I had traded in. The statement listed a $0 liability for everything: wear and tear, disposition fees, remaining payments, mileage, early termination fees, etc. At the bottom, it had an extra line: "Unsatisfied obligations - $1255.00". So after 5 calls directly to Nissan, I finally got someone on the phone who took care of it. You guessed it, they waived the charge. No one could even BEGIN to explain what the charge was for. They had absolutely no idea. So by the end of this, I had dodged nearly $4000 in totally trivial charges from both the dealership AND the corporate office. This shit isn't for the faint of heart. I think this will be my last transaction with any auto dealership whatsoever.
