Ultimately, it depends on how much you want to fork out for such "preventative" measurement and how long you want to keep your car.

With the best scenario, I would say

Fluid:
Engine oil 5k to 10k
Oil filter 5k to 10k
ATF oil 30k
Break fluid (50k?) 60k to 80k
Coolant (40-80k) 100k to 120k
Air-con coolant (80k?) Should be refrigerant and compressor oil, 80k to 100k

Wear and tear:
Battery, Amaron (have it checked annually or show signs of low power, 2-3 years should be)
Air filter (used at own's risk, K&N, slightly dirtier throttle) wash and re-oil every 20k
Cabin filter (50k?)
Spark plugs (Mine 100k)
Engine mounting (100k?) 5 years or 200k*
Engine hoses (?) 5 years or 200k*
Radiator hoses (?) 5 years or 200k*
Tyre (~80-90k for me, light footed) 2 years
Break pad (~120k km for me, don't use break so much, some 20-30k don't know how)
Break disc/ break drum (every 30-50k?) 5 years or 200k
Engine timing chain/ belt (?) belt last 80k to 100k, chain last 5 years or 200k*
Air-con belt (?) 80k to 100k

Parts:
Shock absorber (Around 120k) 5 years or 200k*
Radiator Fan Motor (Around 150k?) 5 years or 200k*
Air con compressor (?) 5 years or 200k*
Air con cooling coil (150k) 5 years or 200k*
Water pump (150k?) 80k to 100k
Fuel pump (150k?) every 5 years or 200k*
Alternator (150-200k?) 5 years or 200k*
Starter (?) 5 years or 200k*
Light bulbs (periodically checking, ~70-80k)
CV joints lubricate every time you do a oil change
Periodically
Overhaul (?) 10 years*
Fuel tank (?) 10 years*

anything with a * is my opinion
