I'm purchasing a C63 2020 coupe and I can't seem to find in the manual what the official service intervals are for the transmission fluid, diff oil, and spark plugs. Can't find it in the manual.

The car only has 9k miles on it so would like to know if there's a time interval as well.
This is for documentation for extended warranty purposes.

This website can give you a good idea!

The services are time or mileage based in 12 months or 10,000 miles intervals, whichever comes first. Spark plugs are due every 5 years or 50k miles. Transmission every 3 years or 30k miles if I remember correctly. Similar for the diff,

There must be something printed and official written down somewhere?

Different model year and not the very detail one found in XENTRY but: https://mbworld.org/forums/c63-c63s-...fo-please.html

Below photos are the MB Required Service Work sheets based on miles or years which ever come first. This was given to me by SM during a previous required Service appointment.
Also included is this year's 6 year service invoice which included a complete Transmission service and B Service. Note: The spark plugs and A service would be required at 5th year or 50k miles which ever comes first.
I have a 2019 C63s coupe.

Thank you! You're a gem.

Looks like the official interval for the 9G is 60k/6y. I'll probably just do that immediately since I'm approaching 6yr.
