I was intent on buying a Leaf, and I wasn't going to let this initial ordeal sour my opinion of the car because it had more to do with the dealership. I knew going into it that getting the car back to Madison was going to be a stretch, and then events conspired to make it a bit more difficult. I think the fact that I made it back in spite of that was actually a point in the Leaf's favor.
Not necessarily only the shortcomings, I was thinking critical as in "analytical", I would have love to read about how the EV experience translated driving out of the dealership for example. It may not be new to you but I've never driven one and would have "extracted value" out of your post if you did describe it ;-)
Most 2013s (all except for the base model) also come with a heat pump instead of a resistive heater, so efficiency of the forced air heater has also improved relative to earlier models (and relative to other similar cars).
For people who live in a mild climate, (sf bay area for me), temporary battery capacity loss due to cold weather, or permanent battery damage due to excessively high ambient temperatures, are not an issue, and given the plethora of chargers in this area, I'd say that almost 100% of the driving my family does outside the daily commute (my wife and I drive separately, and we only have one Leaf), is done with the Leaf. I was skeptical about the car initially, but the leases are inexpensive enough not to worry about and it's been a pleasant surprise.
