Hmm, the car is from California (California car pool lane stickers). I have a 2013S that lost 1 bar at 36k mi, my wife has a 2013 SV bought at the same time as mine with 12 bars and 50k miles, from the SF Bay area. Looks like the car was in a hot part of California to lose a bar at 24k miles. Doesn't look like a good deal to me.
2 LEAFS, bought 1 week apart. 2013 S for me, 2013 SV is wife's. Both manufactured May 2013. I lost first bar at 36,000. Wife still has all bars at 50,000.
