Also, the pricing on the Focus EV just came out the other day. It is going to start at $39,900. The Volt doesn't look too bad compared to that.
The Mitsubishi I-miev is the only reasonably priced EV around, possibly the Leaf. Even the Plugin Prius with only 14 miles of EV range is starting at $32k.
