Beware if car is over 60k (real mileage not temprered)

My car after 60k, need to spend for major services (normal) battery replacement (normal) tayar (normal) although my tayar no need to change at 60k because already change at 40k. Radiator fan relay around rm50 (not normal). Aircond fusebox (not normal luckily still under warranty). If turbo have to see oil cooler hose already replace or not.

I think just prepare at least additional 5k
