I too have been shopping for a good deal on a used Leaf here in C Fla. OP, hope you are not too disappointed, losing the car. I have watched as the local (50 mi radius) of used Leafs has shrunk drastically over the last month or so. I test drove a 12 SL last week with less than 5K miles and passed because I felt the dealer was asking too much OTD.
I've decided that I am not going to settle anymore. If I am going to buy it will be what I want, in the color I want it and not what the dealer happens to have. I am not alone in my endeavors as evidenced by the drop in quality used vehicles. IMHO the used Leaf market is heating up and depreciation may be slowing, stabilizing prices.
