All of the above results from getting tagged in the rear by some airhead on a cellphone:
The rear window wiper on my new MB Wagon wipes the metal tailgate, not the window. This was an OEM part from Germany. Must've been a schnapps break. Motor installed bass-ackwards.
Here's another MB engineering joke -- the airbags failed to operate yet the MB version of Onstar did contact the police.
Here's another MB engineering joke -- as a result of the collision all the seatbelts had to be replaced -- you can't get MB seatbelts in the U.S. from MBUSA -- they have to be ordered from Germany and the boxes have been incorrectly labeled in Germany such that left and right components are in the wrong boxes.
Here's another MB engineering/supply chain joke -- there were no rear bumpers in stock in the U.S. -- had to be airfreighted from Germany.
And here's a Siemens engineering joke -- the GPS system was replaced 3 times before it worked correctly.
