Deal too good to be true?

RunNgun

I've leased 3 brand new nissans from the same dealership, and on my most recent lease am suffering a little buyers remorse. I leased a white altima when what I really wanted was a black 370z. I'm 18 months into a 39 month lease and I want out. I talked to the sales manager and he's claiming he'll pay off my lease, and put me in a brand new leased 2011 black 370z stock model with AT for $500/month, no money down. Obviously on the altima I put $4000 down, but I dont want it anymore and I owe 23k left. The Z's MSRP is something like 33k. He didnt give me the interest rate or even what he's actually selling it to me for, he just said he doesnt want me to be unhappy and values my continued business, since they expect me to lease future cars of course.

So the question is, does this sound like a good deal? Obviously I'll want the money factor and sale price in writing, because if I feel like I'm getting ripped off (I have a 747 credit score) then I could further reduce my payments. But I'm effectively bailing out of an existing lease, and going into a new one with no money down. I made careful attention to tell him I know the standard procedure for the dealership is to buy off the lease, calculate the difference between their appraisal and what I owe, and just tack it on to my new lease, effectively leasing me a 33k car for 36k or something in that neighborhood. I told him that wont fly with me, and that I am looking for the dealership to do me a favor if they truly value me as a customer, by giving me near full value for the car, thus making almost no profit for themselves on the Altima. Otherwise in 2013 when I go to return my Altima, I probably wont be leasing any more from them simply because the experience will have been soured.

This is all pretty unorthodox isnt it? I suppose the initial down payment is a bit of a wash, but I did put 16k miles on that car so its equity has been used up some.

What do you guys think? Are they playing for me here? Or just playing me.
