MB Prepaid Maintenance Package vs Pep Boys / Other
Im almost due for my next maintenance and had 3 questions:
1. Should I go by years or by miles when scheduling maintenance sessions? Meaning if I come upon my next year or ownership but haven’t used it 10k since the last maintenance performed, should I do the maintenance or wait until it hits 50k miles?
2. The prepaid option my MB is either 2 services @ $1630 ($830 per) or 3 services @ $2290 ($763 per). Can I just bring this to pep boys and have them do the same work for less? Attached is the List of what MB performs for the above service.
3. I called pep boys and they didn’t know what the “Activated charcoal combination filter replacement” is. Any assistance with that?
And also what is the dust filter replacement? Is that the interior filter vs the entire air filter?
Sorry all - not a big car guy. But even less of a get ripped off guy.
Any help / tips is much appreciated!
but engine oil 5w40 every 5~7k miles at any oil place.
Spark plugs / transmission oil / rear differential fluid.. maybe at 100k miles.
Charcoal? Forget it. Check it only if you get a charcoal related error code future.




My Wife's '19 GLC only has 23,000 miles, and she goes in annually. At 6 years (bought 12/18), they did the 6yr/60k service, including tranny flush.
