Even at 22k, that is a lot for most people. Online it says the LEAF can go 150 miles for around $4.80. Your payment would be around $375ish a month with at least $100 for insurance (probably more).
Why would most people do that when they can get a used car cheaper or keep driving what they have. It is just expensive (i am not saying i would not like a Nissian LEAF, that would be sweet).
I guess i see people buying EV's and ask why the rest of the world is not (i know you are not asking this, but a lot of comments i read are) when we cannot afford them.
