We have (had) two '15 Spark EVs (my daughter wrecked hers on the snow last week) and my wife just added a Bolt in November. She always had range anxiety driving the Sparks so the Bolt was the only option for another EV. It's an LT with comfort and safety packages, MSRP was about $39.4K, we bargained down to $32K, so with Fed and MD tax incentives the final price was $21.5k before destination, taxes, etc.
The two models are very similar and getting up to speed in the Bolt was easy. I like the display on the Spark better, like the Bolt's regenerative braking better (driving in L), but the Bolt has two shortcomings: The seats are OK with me but not for people with wide butts or wide shoulders, and the Spark is much more maneuverable in big city traffic.
I was halfway hoping she wouldn't like the Bolt so much and I'd get a chance to drive it once in a while. No way!
