My dealer (Pleasanton CA) was quoting $1800 for a 50k service on a GLS. I had him do the A service instead ($199, which is still 2x higher than indy shop) as I'm not quite at 50k.
Do you really have to change Mercedes spark plugs at 50k? That seems really low compared to BMW and others that go 100k.

50K Spark Plug change for 2L Turbos is very common across manufacturers. Some might stretch it to 60K.

Service A: Engine Oil + Oil Filter + Cabin Air Filter + Engine Air Filter (Pre + Post) + Wiper Blades for $200 is a GREAT with all OEM Parts. OEM Parts alone from the cheapest online sellers will cost more than $200.

I just changed mine at home with NGK (OEM) spark plugs at 56K miles, cost $45, labor $0 with standard tools; took one hour or so. They look pretty clean for 56K, I bet you could wait till 75-80K.

C400 and other 3.0TT motors should be at 46k miles. I wouldn't push too much past mileage, the new mercedes motors uses a waste spark fire where the plug fires up to 5 times per piston stroke which puts a lot more use on the plugs (and coils) than say a toyota w/100k mile interval. Even the ML350 has the same interval, and its not forced induction.
Get the OEM plugs online and DIY. Not much to it on the W205 I4/V6 assuming you have done plugs on other cars before. C63 might be more PITA, not sure how far back the last 2 plugs are.

"Properly functioning spark plugs for instance are important for the service life of the catalysts. Failure to properly perform the specified maintenance jobs may adversely affect the emission control system on the vehicle and reduce its service life."

also a 2015 C300 owner, thought I’d add in here that I recently took my car for B service at the Dealer, they told me $541 for the spark plug replacement 😂 insane

Just had the 50K service A done on my 2015 C300.
Dealer recommended changing spark plugs for $550. When I pushed for details, the breakdown was $100 for 4 spark plugs ( Q-4-15-0038) and 2.5 hrs of labor.
Has anyone else replaced the plugs at 50K miles and what was the cost? I thought spark plugs had a much longer life than 50K miles..

well, i just spent $4500 repair on my 2016 C450 AMG with 145k miles. the engine light is on, scanner shows code P2279 Intake Air System Leak Bank 1.
that loaner lady must had seen my work order estimate, i asked her can i have a better loaner than EQB. she said there's a EQS580, so i took it ! i gave her 10$ tip for giving me a nice loaner.
yeah, dealer probably ripped me off but i atleast i have driven the electric S class, EQS580

I did my own Sparkplugs on my C450/C50 and made a video about it for Youtube however I deleted it. I know I was the only Youtuber that showed how to do this job and what parts you needed to get the further back Sparkplugs. The main issue with the big 6v engine is that you need a thin wall long socket and the recommend one is the same as the BMW version. It has a swivel and trust me, you will need it for the 6v and v8 engines.
