Steve 5pts I have owned my volt for 5 months and 3900 miles and I have used only 5.7 gallons of gas! When I used gas it got 38 miles per gallon city or highway! I am thrilled with it so far and in Colorado I received a total tax credit of $13500. resulting in a net cost of $29,000. I only spend $.45 cents per KW so spending $15 dollars a month on charging is worth it.
