SEVERAL TIMES I HAVE NOTICED A STRONG ODOR OF GASOLINE INSIDE THE CAR AFTER FILLING UP AT THE GAS STATION. I HAVE NOTICED SEVERAL OTHER COMPLAINTS OF THE SAME NATURE. I NOTICED A RECALL # 2008-02001 SEEMS TO ADDRESS THIS MERCEDES-BENZ ISSUE BUT AM NOT SURE IT APPLIES TO THE CLS500. I THINK IT APPLIES TO THE CLS550 AND THE E-TYPE BUT IT SHOULD APPLY TO THE CLS500 SINCE THE UNDERPINNINGS OF THIS CAR IS THE E-TYPE. PLEASE ASSIST AS I WOULD LIKE TO HAVE THIS SAFETY ISSUE ADDRESSED BY MERCEDES-BENZ AND JUDGING FROM THE NUMBER OF COMPLAINTS FEEL THAT MERCEDES-BENZ SHOULD CORRECT THIS APPARENT DEFECT AT NO CHARGE. *TR
