Despite starting this thread, I gave up on the Leaf for now. (anyone need a charger?)
I'm back in an Altima after having both the 2012 and 2013 Leafs (license plate AC POWR if anyone saw them around town).
I too live in O'Fallon MO.. I work in Maryland Heights.
The cold weather range was one of the largest issues I felt, especially on slow traffic days.. I was always overly conservative about not running main heat on those days. I relied on pre-heating the car and then using mostly steering wheel and seat heat after that.. but there have been days where I've been freezing (like the ultra-icy day last year when it took 3 hours to cover that distance).
I think Nissan certainly did good at helping to get the idea of electric cars out there, but I'm not going to be rushing back.
I like the "jump in and go" of gas again, not having to get home and swap to the minivan to go back out, etc.
..and yes, I have a 240V charger still if anyone wants to make an offer.
