Brake question!!
You only need to replace the rotors if they are warped or otherwise damaged. If your car stops smoothly, no need to worry about them. Your dealer is being honest about not turning them: MBZ does not approve turning rotors, if they're warped, they spec replacement.
I did a step-by-step pictorial post re: the 210 and it's almost identical on the 208, the link is: https://mbworld.org/forums/e-class-w210/107227-okay-brake-job.html.
If you've done disc brakes on other cars, you won't find anything particularly challenging about the benz discs. Just don't forget to get new sensors -- especially once you've gotten the warning and they are very cheap -- and MBZ brake paste, one packet for each wheelset.
Take care and enjoy the ride,

Greg
