Estimated retail price: $13,015-$15,825. The Kia Soul EV may not be easy to find in the used market, as sales when new were limited to California, Georgia, Hawaii, Oregon, Texas, and Washington, but the effort would be well spent. It affords a roomy cabin, funky styling, and a utilitarian nature. With a 93-mile range on a charge, it gets the equivalent of 120/92-MPG with an operating cost of $1.04 for every 25 miles driven.
