oil change
Also, I've personally had bad experiences with previous cars at JL (e.g. cross-threaded oil filters). I'm not saying every JL technician is careless, or that there aren't careless MB techs out there, but JL techs are more likely to be rushed and focus more on getting the job done quickly than getting it done right.
Lastly, these are very complicated cars. An oil change tech isn't going to do all or the checks that a MB tech will check during an A/B service.
If you're looking to save money, you could look for independent shops who specialize in Mercedes. They're usually cheaper than the dealership, but still a lot more knowledgeable about your car than a quick-lube shop.
