I reckon the workshop guy just use rule of thumb. No different from guideline of changing engine oil after 10,000km.So human reached 50 must definitely go surgery?
Bro, thanks for your advice. That is why I am trying to check here whether anyone has good recommended workshop so that I can send in my car to validate whether the items need to be replaced.I think that you better find another workshop to check 1st before just replacing stuff that doesn't need replacing.
