I had a real problem trying to find a upper bumper protection guard for my wagon so I bought one for a Lincoln wagon and modified it. Cut the lower left corners, at angles and cut off around 1/2 inch of the upper part, done in 10 min. a pair of shears. Easy. 60 bucks on Amazon.
plastic cuts very nicely, it's not perfect but short of ordering one shipped from England for over $300.00 it's the best thing I could come up with. Seems that no aftermarket companies in the USA makes these for the Wagons, Searched all over, even asked the parts dept at Mercedes, no luck. So this was my solution.
