I almost got one from carmax. "IF" you still want a leaf, carmax is perhaps a better way to do it. They usually have photos that include a picture of the dash with the battery SOH bars on the older models. Plus you can transfer a car you like to your nearest one for free or a small fee. I saw some 2015's on there recently for about 10-13k. The guy at Palmdale even let me check the car with leafspy. Just get yourself the OBII dongle and the free version of leafspy.
The only reason I didn't go through and get a used 2015 was that I scored a great deal on a new leftover 2018.
