 We had a 2013 LEAF. we used to have the 2011 for 2 years and many wants have been added to the 2013 like ECO mode stays on, braking mode. Also better estimate of range. The Air Cond is also more efficient.  The only BIG problem is the battery degrades in the heat. The 2011 thru 2014 have the same fatal problem. We lose 5-10% capacity a summer. It's lost forever. The warranty is sticky you have to lose 4 bars about 40% with in 60K miles and 5 years. They changed the software so that doesn't work and you lose 3. Yet range is bad and you can't drive. We used to love our LEAF. We lease and every 2 years can't wait to see how they improve it and lower the cost. Our daily commute is 44 miles round trip. It's easy with 50 60 left each trip. I can go about 70 miles on city streets when needed. Just lease so you don't get stuck with a LEAF with a low capacity battery pack. New models get lower pricing so selling your old one would be hard. The new 2018 LEAF will have more range. Near the end of 2018 it may top 200 miles but they haven't added Thermal battery control so I would not buy one. We now have a 2015 KIA SOUL EV that has Air Battery cooling. It is also failing. Only vehicles with liquid cooling like the Chevy SPARK EV , Bolt, or FORD FOCUS EV and world Leader Tesla model S , X and 3 have long long battery life and no heat problems.
