Anyone using Volt for long daily commute? (120mi + round trip?)

[gstmike]

Just curious if anyone is using their Volt for long commutes to work on a daily basis. My commute is 160mi/day round trip. Mostly freeway. I'm considering a Volt. I think I can charge at work as well. Is anyone doing a similar commute?
What concerns should I have? If I break down the gas savings over 5 years the cost of ownership is comparable to a similar car in the $25K price range that gets 38mpg (the Cruze for example). Just not sure how concerned I should be about putting 30K mi per year on this car so looking for people with high miles on their Volt and their experience.

Thanks all...
