I think this is an ideal situation for a LEAF. The climate is not that hot (90 degrees F) or cold (60 degrees F), distances are short, speeds are low, roads are flat.
The car you're looking at has very low mileage. And if used in Japan, not exposed to the continuous, searing, dry heat of the US Southwest where all the battery degradation issues seem to cluster.
You can check if it's set for 80% charge by pushing the blue button on the right side of the center stack, and selecting "charging timer." Then select "set timer 1" and on the next menu select "Charging %."
Also, if the A/C is on when the car is turned on the estimated distance will read lower than if the the A/C is off.
Sounds like an ideal car for you! Go for it! Imagine never having to buy gas again! You're going to love it.
