I think they show you the choices and let you choose. The oil filter is where you can go wrong. They are not going to have the proper filter. They will have one that fits, but who knows what the quality of that filter really is.

Lots of info about oil filters on the net. I would definitely educate myself, by the proper high quality filter, and bring it with me.

A better alternative would be to find a MB independent shop and have them change your oil. I would never trust the quick lube places with my MB.
