Probably can make a poll and ask how many ZTHian does actually skim brake rotor when replace pads and rotor replaced on the 4th pads replacement, how many people ever replace full set of bushings for the car handling parts/under carriage on a car that from 7-20 years, and who did actually replaced handbrake line before it snapped? Who did replace the brake caliper pistons and seals before accidentally found out that one of the piston jammed? :hmmmm: Of cause, would like to add those who got a tiny brake rotor and replace the factory 14" wheel to 17-18" or stretch a 215 tire onto a 9" wheel. All these are very general maintenance. there are plenty more which some of them you don't even hear before, eq like: MPI test chassis and handling/brake parts, suspension system calibration, sensors calibration and etc. Even a Defi gauge, it suppose to be calibrated every year together with the sensor attached to it, according to the general industrial standard. Those general thing like replace glass pack for muffler, replace entire engine wiring harness, engine tuning (not those 'judge engine condition by ear' type), and etc are quite common. And to be honest, i still not yet complete an inspection/maintenance/upgrade list for my own wira. Due to the car is old, many things have to be fix and upgrade to match today's safety and environment protection standard. So if ZTH has 100k members who seriously take care of their car, now left 99999 only. That total definitely not match 5% of the amount of Malaysian drivers..........in KL alone. + other states, the average could be pulled under 0.x% or even less. Truck/lorry driver? if see one really take responsibility on the safety/environment by caring about the maintenance, you should quick quick go and buy toto 6D or big sweep. If 10% of ZTHians do take care of the car seriously, we can sacrifice a chicken for thanking the god.
