Yep, MB used to include this tool in the trunk bag of most cars, then later, in the trunk of the fancy cars like w100s and 109s and maybe some SLs. Now the cars are almost entirely made of either grey or black plastic and you dont need no 'stinkin tools...well other than an SDS laptop. My buddy works at Schumacher MB in Scottsdale. Says 99% or more of the work they do is software related. He says the cars are shipped with known software issues! Boy, have things changed! Remember when an MB ashtray consisted of MANY parts, some steel, some chromed, some leather or wood? Now, 1 piece of blow-moulded grey plastic! No more annoying grease zirks etc! And 11000 mile oil change intervals (as though the oil doesnt still get dirty) But at least the door mirrors point at the ground when you select reverse! Now, back to the wrench for trans/diff. I have them if anyone needs one. Keith 520-404-2875
