It's more likely percentage of number of parts and not of the value of the car. In the number of parts, percentage is high cause of many basic plastic and metal parts being locally made, but the actual high value items like engines, transmissions, electronics, suspensions, etc are all imported. That's why assembly of CKD units is still a loss for Pakistan and there being zero export of our assembled cars doesn't help either.
On the other hand our neighbour India has localised a lot of the car production and have become a car export hub, and we can all see how much better they're doing. Same is the case with most other manufacturing in our country besides textile, manufacturing is just at a very basic level to barely meet local demand and local "business tycoons" keep on influencing the government to keep giving incentives for just basic manufacturing with minimal localisation and no export plans.
