The best move on a Leaf is probably to find an MY12, offer nothing (because they are worth NOTHING), and then pay for the upgraded battery pack yourself.

Anything that says “below” at that age and miles is most likely electrical or battery issues, not wrecks. Notice they are effectively worthless. Offer the dealer these valuations plus a pack and explain you know the score because 28 told ya, and I said GFY on high pricing. My guess is dealers are taking these in on trade, they need a battery pack which either exceeds or nearly exceeds the value of the car, and they get stuck with them. If you, the enterprising buyer, understand this and have no problem getting into one for roughly 10K all in (buy plus battery pack) it may not be a horrible proposition for a short range commuter.

Years back cars like these would be bundled in packs to wholesalers, i.e. buy these five cars for X price, but only three of the five were ones you wanted. This might also be what’s happening here, dealers offload these things in packs to a wholesaler, who makes a per unit profit (i.e. breaks even/minor profit on a CR-V but makes high profit on the Leaf they get for the equivalent of a grand). I am not sure if this still is the case with wholesaler deals, but assume so.
