When considering buying an EV or PHEV, be sure to also check local incentives as well as Federal and State.
My county just launched a program whereby they give county residents a voucher to buy an EV or PHEV through an in-county dealer. In addition to the voucher amount (upto $2,200 off), they negotiated with the dealer to provide at least an equal amount discount from MSRP. The later is moot for Leaf as those already have $4k NMAC cash off. But for other models, getting the dealer to provide a $2,200 discount and then getting $2,200 from the county in addition to the Federal and State incentives can be real nice.
And even for the Leaf, this voucher would save you $2,200.
Don't know how many counties/cities have incentives. But it is worth finding out and factoring that into your purchase/lease considerations.
