I am now going over 100 000 kms with my C63.
Thinking about switching from regular dealer to "Indy".

Does anyone have list of what to do on car at next services?
I did spark plugs around 70 000km, oil + all filters every 10 000km..

Car has no problems (also tuned for 30 000km without issue)

I'm surprised you haven't switched from a MB dealer to an independent shop as soon as your warranty was out. You should shorten up the oil change interval to every 5k miles, that is what I have done as it is cheap insurance against gunk building up in the oil lines with the hot-V turbo setup. When was the last time you checked the brake pads and rotors, or changed the brake fluid? That may be needed depending on the last time the fluid was changed. You may also be due for a transmission oil & filter and rear differential oil change. If you do a search you should be able to find a link to the service manual which has the service intervals.

I get email Specials from one of the local MB Dealership, my C63s coupe is a 2019 with just over 12,000 miles so this email will not apply to me, but this one I received today may help you as it address recommended time frames for suspension and other key components that need to be serviced or replaced. See /attachment/photo.

Transmission oil done at 70000kms.
Brake fluid every 15000kms.

Checked suspension yesterday and its rock solid!

This smacks of "fear-based"/FUD marketing strategies, which I find offensive.

WRT alignment ... relative to your driving habits, is your tire wear uneven and/or excessive?

WRT shocks ... do the simple "push car body down -- is the rebound dampened" test (compare to new car in showroom, if you're in doubt) and the "is the ride still firm/controlled or is it getting 'floaty'" monitoring.

WRT power steering pump ... WTF, not even present in cars with electric-motor steering.

So where to find service manual in PDF? Thanks

@notabenex here is a link. just look at the correct column for model specific items required.
