I have the 2013 Nissan Leaf. Wow what a car. If it only had a 40KWH battery I would buy another one. The reliability of the
leaf is amazing. People will be drive those cars forever and I am sure there will be after market batteries for the leaf down the road.
I have been very happy with my 2015 Leaf as well. I just really needed something with more range as the Leaf is basically only useful for commuting back and forth to work. I can't even make it to the airport and back from my house in the winter without charging at the airport. I also wanted to get back to a higher end car. Even though the Leaf is nice, it isn't a luxury car by any stretch.
