My experience with the Volt was overall very negative. Its WELL overpriced, underpowered, and only achieves about 30 miles with realistic everyday use. The gasoline engine is not important to me, I would strongly prefer something that has 100+ Mile range and is more powerful. In this price range, spring for the VASTLY superior Tesla Model S.
I have never driven a Leaf, but its a lot faster, and quite a bit cheaper as well. Might be a feasible option if you can get a hefty amount back in your state. Still a bit spendy, but not a bad car, and its faster than your average super cheap car, which is never bad.
Overall I do look forward to being able to purchase a cheap electric car capable of a few hundred miles, but it ABSOLUTELY MUST be faster than your average 10 second to 60 ecobox. That kind of low performance should not be tolerated, even for a daily driver. Something like 6-8 seconds to 60 is acceptable, and so long as it can hit 100 MPH, thats enough. What I like most is the lack of a transmission clunking through gears, or a manual that can be tiresome in heavy traffic. Throw in the fact that you can slam it WOT right after you turn it on, have the A/C or heat cranked with the thing in your garage, and a decent smartphone app allowing me to cool/heat the cabin remotely, and its a winner.
