We bought a 2013! Better rebates and financing and identical to the 2014 as far as we could see! The Energi's only came out in 2013, so we weren't surprised there were still some on dealers' lots. However, from what I have been observing, there are fewer available now than when we purchased!!
With regards to charging: We had our electrician install a dedicated 110 outlet. Works fine! We are up to full charge in about 7 hours. Takes 7.5 kw, which costs us way less than a dollar for 20+ miles. Since we mostly charge overnight, haven't seen the necessity to pay for the 240v yet!
