I saw a w140 drive by today and the trunk said "300SD," NOT "350SD." I thought Mercedes only put the 3.5 liter in the w140, but I could be wrong. Does anyone know if there were some years they put something besides the "rod-bender" in the w140? I always loved those cars, but I know better than to buy a diesel version.
