Update (If anyone was curious ):
I ended up purchasing a 2015 Spark EV from Carvana, in January of this year. It had 16,500 miles on it when purchased, and now has just over 28,000 miles on it. I test drove an I-MIEV in Atlanta, GA late in 2017, and even though I loved the look of it and the overall feel, I determined that the range and efficiency at highway speeds would be prohibitive for my needs.
I enjoy watching the "KiwiEV" channel on YouTube, which led me back here looking for battery capacity info (easy to find, thanks guys!). Just thought I'd stop by and drop a couple of lines.
Thank you for the good & honest information that everyone who responded in this thread provided, it is and was greatly appreciated.
