I understand that. Sometimes leasing is a good way to buy a car, though, as you don't have to decide whether or not you want to own it for several years. Also, most people don't qualify for the full Federal EV tax credit if they buy. I wasn't suggesting that the OP buy his car, but was saying that the deal he got was good IF he planned to buy the car. If he turns it in then he'll have wasted some money because of the unnecessarily low residual.
This was exactly my situation. Couldn't take advantage of the Federal rebate because of income, but Nissan offered $9500 lease rebate and CO offered $2500. $12000 off after negotiating $4000 of MSRP. Our lease payment is low and the residual is low. Perfect for us as we intend to buy it at the end of our lease. Total cost with fees, registration and taxes for the lease amount came to about $21500 for an SV.
