This is a universal fact, anywhere in the world a publicily sold machine like a car has a solid standing of "service and spare parts" with full inventory access of parts and "knowledge base" - that is why companies like Toyota, Nissan, Subaru, Honda, Mercedes Benz, Volkswagen, BMW, GM, Ford etc succeed.
in Pakistan the only 3 manufacturers who succeeded followed that exact principle, The rest who are selling chev, Nissan, Ssangyong etc sold a few cars and packed up their business - I call this "khaip maal" - Furthermore our lovely people still think that car repair and service is done by illiterate people who never went to school or even have a family background so they expect repairs to be Rs 2/- part and Rs 1/- labor and they can cuss them out later on - The immediate question asked is "yaar is to jugaad kardo bus 2 ghantey ke liye"
The above and what Capsat posted is a perfect bitter soup that makes car ownership a true horror in Pakistan. Sadly the ullu ke patthay customs duties and other stupid taxes are implied as if either Pakistan has the most amazing and truly standard defacto transport system. The duties are to force people not to buy any cars at all - Its there since the Raj because they implied that anything not made in Britain should be taxed heavily because Britain makes "everything" - they did at that time - Pakistan is now not part of British empire and our transport is worse than pig feces - There must be some other form of economic growth that has transport missing from its picture - which no-one on earth knows about - but its being followed in Pakistan.
