I recently purchased a 2012 SL with ~ 25,000 miles in like new condition (except the battery) for $9500 US. I've put 1700 miles on it in 3.5 months. I have an OpenEVSE charger (L2) wired to a 30 amp 240 volt ganged breaker. I used the L1 charger for a couple of weeks and used a DC/QC charger once - mainly for the experience. Totals on the OE charger shows ~400 KWH. That's less than $50 of electricity.
I live in Southeast Texas (HOT!) and the Leaf spent it's life in this area. I expect to get a replacement battery before the warranty is out as the Leaf has 9 bars at this time. Two hot summers should get that last bar! It's not guaranteed, but will be "icing on the cake" if I do.
I can consistently get 55 - 60 miles of range on a charge - seems almost regardless of how I drive (??). However, I do take it to the very lowest limit of remaining miles (had to push it down my street one time). I can do this in my area because there are dozens of charging stations and I use it mainly for local errands. I do have a 25 mile round trip commute to work - but only go in to the office once/week. I can do lunch and errands without any worry.
I own a high mileage Suburban for trips to my rural property (big loads). I do not use it around town anymore. I figure I've saved over 100 gallons of gasoline in the 3.5 months!
Very happy with the full features of the Leaf and especially the way it has maintained it's freshness - like a new car. Also, more fun to drive than a Prius (my Daughter has one). I'd say MUCH more fun. The Suburban now feels like a whale that has Parkinson's disease (no transmission shifts in the Leaf). The only disappointment is not having the 6KW charger - that was available in the 2013 + models, I believe. I would be able to charge in almost half the time with the OE charger.
To be truthful, I bought the Leaf for the battery - and will eventually use if for off-grid backup at my rural property (I'm a tinkerer). However, I drive it everywhere that is possible within the limits of passengers and miles because I enjoy it.
Hope my limited experience helps.
