well, I have a 2014 iMiEV and a 2016 Volt, and the iMiEV definitely has its place. The handling is great and very decent acceleration. I live in the Santa Cruz Mountain at 2200-ft and round trip commute is 50-mile. I particularly appreciate the level 3 as it can be topped off very quickly. I've seen a recent listing at ~$20K, thus $10K after incentives, makes it a worthwhile consideration. And if you live in the Central Valley, San Joaquin, there is an additional $3K off.
I would choose the iMiEV over the SmartEV any day, being 4-door and 4-seater. So yeah, I think it's worth adding to the spreadsheet.
I am now debating between the Bolt & M3, but the lean is toward the Bolt as of today.
