Great thread to start just as I'm coming down from really wanting an EV again (happens every couple months). :P
My "dream" (possibly affordable to me in the near future) EV is a Bolt, it could pretty easily replace the Prius. Any other Prius replacement would have to be a PHEV/range extender. I've considered just getting the Prius a buddy and having 2 cars. I'm leaning towards a Spark EV, but the cheaper ones don't seem to have fast charging (a must if I want to go outside of my city), so a Leaf may be a better fit for my wallet. Would have to be a 2013+ with heat pump, I've read too much about 2011's and 2012's battery issues.
There's several Smarts near me for $4500-6000, a couple i-MiEVs for $5500 and $6k, Leafs from $6500, Fiat 500e for $8k-8500, Spark EV for $9.5-10k, C-Max Energi for $12k, i3 as low as $18k. Prices are from local news site's classifieds,
www.ksl.com/auto/ , much higher use than Craigslist in Utah.
