Well said Lung sir. Owning a driving experience for 30+ years, it is reckoned that preventive maintenance is a must! I replace battery regularly in every 3 years. I pick AGM main stream brand only, battery fails all in sudden in the middle of the road would cause danger leading to a fatal error. Parts to be original including lubricants; filters; brake pads and discs may be relatively costly but justified for the expensive repair afterwards remedying failure due to the worn/indecent aftermarket parts.
