Spy shots: 2010 Mercedes Benz R-Class facelift

Sales figures for the R-Class haven't managed to live up to the expectations of the German luxury brand, but Mercedes Benz is determined not to completely write-off its 'Grand Sport Tourer' just yet. The R-Class received a mild facelift last year to help turnaround flagging sales, but a second and more extensive update is in fact planned for the 2010 model year as previewed by these latest spy shots of a prototype caught testing in Germany.
