I think it's a great car, and when you think about it, it's a much better fit for the majority of people's lifestyles. My commute is short enough so that I rarely need to use gas. One tank has lasted me 3 months so far and I haven't even used half the tank yet. However, it's great knowing that I can use it when needed, and thus I never get "range anxiety".
Also, since the electric range on my Volt is 40 miles, I didn't need to install any special electrical equipment. I just charge it on a normal 110 volt outlet (I set the charging to 12 amps which is fine on this outlet because it's the only thing on it) and it easily charges overnight.
I really do think the Volt merges the best of both worlds, and while I do think that all-electric is the future, for the time-being a plug-in hybrid is really a better option for most people IMO.
