#1 your 2015 will have cruise control and B mode. Now how you decide to drive is up to you but I think (and I am guessing if its hot for you this past week as it was for us) your best bet is getting the car with the better battery. you will lose efficient heating but you can easily get away with wearing a coat and using the seat heaters and being comfortable enough. granted that is a personal decision you have to make
other than that, its NAV and other ammenities that I think you could easily do without
otoh; they are cutting the price big time on the 2014 so a great opp to get the features for cheap but $50 is $50. up to you to decide whether its worth the 2 extra grand.
as for me? I would not hesitate to take the cheaper and newer option but guessing my decision is based a lot on my income level
Given the OP's daily commute needs and the fact that they're leasing not buying, Either car will work. The heat pump (available SV/SL only) is nice here in the Bay Area, because our mild winters mean you will never need to use the resistive heater that sucks up range. If you had a longer commute or were buying I'd say opt for a car with the heat pump for sure.
As mentioned, the 2015 S includes B mode and the cruise control, so those aren't issues. Really, it comes down to what minor amenities the OP cares about - do they want the all around display and assorted other options that are only available on the SV and/or SL? Personally, I recommend people get the SV here if they need to maximize their winter range with the heat pump, the S otherwise. And get QC whichever trim level you choose, unless you _know_ you will only use this car for commuting; you may rarely or never need it, but it's nice to have and gives you the option of taking longer regional trips. The faster L2 charging that comes with the QC upgrade on the S (and is standard with the SV/SL) is also useful for such trips, and if you have a circuit and EVSE at home that can take advantage of it, will also give you added flexibility for short notice trips.
