Haha! Think they cleaned the rear too much and removed all the
stickies but never paste back. 
Even the iconic "Mercedes-Benz" words + metal logo and "Citaro"
name have also gone missing. Now the rear looks
empty...
OMG! You noticed this faster than me! I didn't even notice it
while I was taking the photo! 
Many of them already like that. even SMB136C, Think they will
remove from all soon 
The front of SMB139U also has no more wheel-chair
sticker on the bumper.
