A 2013 Nissan Leaf should get 60-75 miles of range (depending on how much of thebattery you use, as well as climate, and other driving conditions). If it got ~80 miles new, it would still get 60 miles now. That might be enough for someone to make a short commute, though unless they have relatively fast charging at home, a 20+ mile commute 5 days a week might be tough to pull off. But most errands would fall well within the existing / remaining range.
50 mile round trip at 3 miles per kWh would be under 20kWh, or 1.6kW for 12 hours, about the same as a plug in heater on max, easily doable in a normal socket let alone a dedicated charge circuit.
