Our Friend 'DerTuner' just sent us some pictures of what is likely to be an E-Class mule testing on the autobahn in Germany. The Mercedes is highly disguised under a C-Class body. But the larger proportion leave us to think there is an E-Class heart under it. Have fun trying to decode the camouflage and find out clues of what the future E-Class will look like, or is it just a bigger C-class facelift coming up already...
