At one time in the summer of 2008, gas prices average around  $4.50/gallon in the U.S. After the summer of 2008, gas prices plummeted  down to $2.00/gallon and people were beginning to enjoy going out more.  However, as of April 2011, the price is already $4.00/gallon and it is  predicted that it will reach over $5.00/gallon within the next year or  so. 
The best ways to save money is not drive at all and just stay home,  sit in front of your computer all day long! Most of us can't do that  because we must drive to work and we live in a society where driving is a  necessity. How many miles are you getting from a gallon of gas? There  will be no expensive cars in this post and none of the cars here will  reach 0-60 in 5 secs, but these cars will save you money on gas every  year.
