I posted this on another thread
So here is your repost under another topic
This is what your paying for, sometimes at MB rates
Reset maintenance counter in cluster
Replace the following: - activated charcoal filter for A/C
- engine oil and filter
Check the following: - body, underside of vehicle and paint for damage
- brake system/brake hoses for tightness
- disk brake pads for lining thickness
- engine coolant level and strength
- engine, gearbox, tubes and hoses for tightness
- exhaust system for tightness and correct fixation
- horn, interior and exterior lights, warning lights, A/C system, seat heating for proper operation
- parking brake function
- tires and wheels for damage, condition and single-sided wear
- tire pressure, correct if necessary;
LF______ RF______ LR______ RR______
- tire tread depth, enter in mm;
LF______ RF______ LR______ RR______
- windshield washer system fluid level, correct if necessary
- windshield wiper blade condition and wiper/washer system function
All this info and more can be found at

And most dealers include a car wash, although some have reported being charged for car wash soap from what I would then call a stealership
Now if you are 1/2 way handy you can change the oil yourself but that will cost close to $35 for materials + you need the cabin filter. But it may be worth the money to have them reset the maintenance indicator. That can be harder than changing the oil
