That's my plan and would be 3) on your list. For some owners, a Leaf will be a useful value for the indefinite future, unless crashed. I'd still drive my Leaf even if it degraded 50% from its current state. At the present rate of degradation, that point will be long after I'm no longer driving
But I agree about selling them cheap. I'm kicking myself for not buying a Leaf that sold locally for $2500. Unless it was flooded or crashed or something that was a steal, regardless of the SOH of the battery.
