Unless you have a particular need for the slightly longer range, ~6kWh charger, or heat pump, I would advise anyone to buy a used LEAF rather than either buy or lease a new 2013 or 2014 LEAF today.
For ~$15 to $19k you will get virtually the same utility for the next few years, from a well-cared for used LEAF, at a fraction of the TCO of buying or leasing a new LEAF, and taking on the huge depreciation hit of the first two or three years of use.
Sometime between 2015 and 2017 a second gen LEAF will be introduced which will almost certainly be significantly improved over the three-year old gen 1 LEAF design.
And there may even be a competing BEV on the market in the same one-to-three-year time frame that is an even better buy than a gen 2 LEAF.
Who knows, maybe Tesla will actually come through on its promise to produce an "affordable" BEV?
In terms of my own outlook for the first competing BEV producing a significant improvement over my 2011 LEAF, the i3 currently looks most likely-to-succeed. If final pricing/real-world-mountain-range results look good,
and DC charging shows up, either with the installation of SAE stations, or availability of a SAE-to-CHAdeMO adapter, I might get interested in the "ultimate
electric driving machine "
Not a plug, I don't know the seller or his LEAF, but I think forum the forum ad below is a good representation of the excellent buys in the used LEAF market today:
