I haven't had my Leaf very long. I haven't measured my power usage from charging the Leaf. In the short time I have had mine, I have looked at my daily electrical power usage. My charging usage is un-noticeable as it is washed out by the differences in my house heat pump usage in cold or hot weather. I currently pay a flat rate of about .085 per KWH.
In rough terms though - I figure I will have payed about $23 K net for a 2015 SV with LED & QC option and a L2 charge station with all the rebates, tax incentives, dealer adds, taxes, registration, etc. I live in a hot climate, so I am already budgeting for a battery replacement @ $ 6 K in 5 -6 years. That puts me at $29 K for a small car with limited range. With gas and maintenance costs, I will probably be a little under what a similar size ICE car would cost but not a lot.
It's a nice little car that is fun to drive, so I don't really regret my decision to buy one, but I don't know that I would say that it is an inexpensive car to buy.
