late reply but there is more to this story.
car repair in Pakistan has boiled down to 95% scrapped parts (including screws), how many cars can you point out on the road that have been repaired 100% with OE genuine factory parts?
the other factor is that the average car owner is still stuck in a mentality of viewing a car as a luxury item and hence are still stuck in showoff, resale, plastic on seats and other silly things including meter tampering to keep the resale up.
The deepest factor is that there is less than 1% of car owners in Pakistan who actually appreciate quality work, for them oil change on footpath with recycled oil and newspaper funnel is better than a service bay or even service pit oil change. They dont care if the technician is using plumbing and carpentry tools on the car. e.g. tappet setting on old engines can be done by hawaee tukka OR you can do it correctly - naturally one is cheaper than the other.
Another factor, there is a different approach to working on german cars as compared to japanese ones, in Japanese cars you sort of make a space to jam your hands in it to repair, its somewhat doable in german cars but if you stop and take a look you can make your life 100 times easier if you remove a few assemblies to make all the room you want. There is also a factor of tooling. A good mechanic would have a full toolset with multiple styles of tools - most mechanics in Pakistan only buy a handful and cheap ones to repair japanese ones and call it a day and then go even further to not refer the service manual.
The end result usually is a car held together with sheet metal screws (cut sakroo) and cable ties and nearly every nut/bolt rounded off because of made in rural china tools.
