Honestly as a work beater.. I think you’ll have cheaper maintenance, cheaper up front cost, more selection, And still get respectable mpgs with a w211 gas e320. I use to drive 600 miles a week with a w210 diesel and now with the w124 320 it’s half the operating cost. Ya know actual Total cost per mile to Use the car
