I have had my Gen 1 Leaf Sport for 1 year and have become a devout EVangelist.
There have been no maintenance costs although I do object to the cost of registration but then I am not paying any road user charges, I have since found out charges are changing in July 2017.
I like the smooth quiet operation, the way it goes when required, the quality of the finish and the comfort. Sure the range is a problem but it has only been to Auckland twice and Whangarei 3 times. Other than that it goes 26kms into town everyday, comes home, gets plugged in for a 10amp charge to 80%. Total mileage for the year was 11200kms. As I'm home by 10am it is mostly charged from our PV panels. This normal use is why I bought it in the first place as it satisfies my needs. The meter on my cable outlet shows it averages about 140kw usage a month but as I have mentioned previously I have no way of knowing what is "our" electricity or "theirs".
My other car is a 1966 Riley Kestrel which more than makes up for the Leaf in air pollution!!
