Without going through all those listings, here is what you need to know about the 2013 Leafs:
* If it gets cold where you live, get an SV or SL. Their heatpump heating system uses far less power in Winter temps above 26F or so.
* CHECK THE BUILD DATE!!! This is on the driver's side door jamb sticker, and gives the month and year it was built. Avoid those built before April of 2013, as these have the older battery chemistry and will lose bars quickly. Those built in April or later lose bars much more slowly. The only exception to this advice is if you see an early 2013 car with 8 or 9 capacity bars showing on the dash. These may be eligible for a free new pack installed by Nissan, when the capacity is confirmed to be 8 bars or less, within 5 years and 60k miles of the in service date.
* Cars with Premium Package are worth more. This option consists of the upgraded Bose stereo system, and the excellent 4 camera "Around View" parking monitor system. The car in the first link doesn't have it, so try for a better price if you don't need these options. When looking at photos of Leafs, you can see if it has Premium several ways: by looking at photos of the touchscreen and looking for a button labeled "Camera" at the bottom left, or by looking closely at the Nissan emblem on the nose for a little round camera lens. Yo can also look at the side mirrors for the little camera lenses on the bottom, but these are harder to spot in most photos.
