It has been 2 months since changing over from a truck to a Toyota Prius.  We have put 3,200 miles on the car and are averaging 47 miles per gallon.  Our gas bill has dropped from $1,200 per month to $120 per month.  That is right, 90% drop.  Part of that has to do with the drop in gas but the miles per gallon went from 14 to 47 mpg.

Our next Toyota Prius is 2 weeks away.
