The car that once went by the name ?Cross Country? is today the best-selling Volvo model. After its 2008 overhaul, its sales surpassed those of the XC90 SUV, which had taken the lead for several years. For 2009, Volvo is offering two versions of the XC70, enabling buyers to choose better performance for barely more money. You might want to know that the two versions consume about the same amount of fuel, which could relieve buyers potentially interested by the turbo version.
