I was recently facing the same question, and I decided to buy now. I did this primarily to take advantage of the $10,000 tax credit ($7,500 federal + $2,500 State of California), that will (likely) be disappearing in the next few years. The question, for both you and me: Is the advantage of a, say, 150-mile range in 2017 or 2018 worth paying an extra $7,500 at that time?
Additionally, I am now using about 70-80% less gasoline while only adding 10% to my electric bill, so the economics are working out nicely for us. I also suspect that our maintenance and repair costs will drop substantially, too, but I don't have enough data to support this hope, yet.
I have a 36-mile round trip commute, with free level-1 charging at work, so my 2015 Leaf could easily serve my needs for the next decade, maybe longer. (We also have ICE vehicles for longer trips, when needed.) Your situation and needs may be quite different.
Hope this is helpful.
