The last time I was in my local MB shop my service advisor said I was due a scheduled service pretty soon based on the time elapsed since the last service but when I checked the display in the car it said another 2,500 miles. Should I go ahead and have the service done even though it isn't really due according to the miles or should I wait until it reaches the mile date? We don't drive the car ( 04 E320 33K) that much so the miles come on slowly as compared to the months. Would appreciate any comments....Thanks Desert
