Wanted to give others our buyout result to help you guys negotiate. That way, even if Nissan no longer offers the rebate, you have a point of reference for negotiations.
We had a 2013 Leaf S w/ DC charger for $2,500 down and $256/mo for 36 months, 15k miles/year. The negotiated residual value at the time of contract was $12,179.
We took advantage of the $4,500 rebate in September before it ran out. I called several dealerships in my city and the out-the-door prices varied by several hundred dollars. Only 3 called me back and gave a quote over the phone, nothing in writing. Best was $8,500 out the door, all taxes, fees and tag included. They tried tacking on fees "required by law" (they were not, my husband is a lawyer and they were unable to produce any evidence of such law), and tried getting us to sign the credit application 7 times, saying it was not a credit application. Ummm, it says "credit application" as the title!! I'm so glad we had our financing preapproved at our credit union beforehand.
Don't let them fool you. Stick to the price. Don't let them scare you into signing anything you don't understand or agree to. They tried yelling, being nice, making us wait, etc. My husband took out his laptop to start working and suddenly our paperwork appeared, like magic! They knew we were not going to sit idly for hours and gave our time wasted. Be ready with snacks and things to do.
At the very end, they still tried to play dumb and increase the sales price by $4500 on the actual final sales contract, "forgetting" to include the rebate, after having us sign and agree unofficially to the $8,500 price on 2 different occasions.
It took 2.5 hours, but we did walk out owing $8,500.
To see other leafs for sale, go to Carvana.com and such. Check inventory often. This past week they had a 2014 Leaf S with 7k miles for $11k. Caravana gives you 7 days to test out your car and you can return it without issue if you don't like it. Much better buying experience than dealing with the stealerships! If you know your alternatives, you won't get stuck with a bad deal! Other popular car buying sites include beepi.com, caraguru.com, autotrader.com.
Good luck!!
