Over the next six months, gas prices in the United States are expected to rise to over five dollars per gallon, setting a new record for the cost of gas and making it more difficult for the average commuter to even afford to get to work. Because of these anticipated rises in gas prices, older used vehicles are now increasing in demand, because people want cars that can get more miles to the gallon. Used cars are selling for rates that are well over blue book value, and not just in private sales. Even dealers are getting in on the action and paying out more for trade in value of used cars than they have in years.
