A lot will depend on car, and driving habits. A timing belt may need changing at 80k where a chain may never need it.

Start with the manufacturer recommended (NOT dealer recommended) …

Oil/Filter every 10k (or less);

Brake Fluid every 2 years (you can test this before changing and in my case it’s never needed changing at less that 5 years);

Air Filter/Cabin Filter every 40k;

Spark Plugs 80-100k;

Transmissions Fluid every 80k;

Coolant, again test it, I’ve gone over 200k without issues.

Belts/hoses - check, but maybe 5 years (hoses when you do coolant).
