Get real fellows, he lives in a country on a small island; there are no long distance drives likely; there are no nissan dealers or service centers; he is severely restricted in his selection and choices due to limited number of vehicles available; imported cars are expensive due to high shipping cost; he must make the best of whatever choice, and in the situation that he may be found.
OP: If you can get the Leaf spy app, even the lite version, with a blueteeth OBDII scantool dongle and an android phone, then you could read the actual cell voltages at full and after driving it down toward empty, this could help you avoid a big expense of buying a car with defective cell in the pack which would drastically limit your range. Until you know the cell health then you can't know anything about the pack capacity or remaining life.
