Where to get detailed service manuals




Sorry for the noob question...
I now own 3 Mercedes and have started to take interest in keeping them all properly maintained, and when to do what. My W222 S-Class still goes to the dealership, but I am more interested in the books for my W212 and C207.
So where can I find some easy to read/use service workshop manuals for my MBs? I am not interested in all that VRmachine, zip extracting, and sketchy bootleg BS. Just something where I can see mileage service intervals, torque specs, required oil viscosity and amount of oil.
TIA!
