While the first half of 2009 saw a substantial increase in used vehicle value, RVI Group predicts that 2009 will see a 2% drop from 2008 year-end results. This has to do with worsening economic conditions and a peak in used vehicle stock in the next few months. RVI says that 2012 to 2014 will see the largest increase in used-car pricing when a record low number of used vehicles hits the market.
