I think Pakistan needs a company which should be made keeping one thing in mind, that is to make its base 100% local in three -four years.
Initially a good car from outside could be picked with technology transfer and complete plant & assy line, redo its show design or get it done from specialists. They should involve maximum no of local vendors to localise the components on war footing.
Volumes have to kept high to get economy of scale. This could be done by having buy back arrangements with the Parent companies.
Along side the Company should keep pace to improve the model every 6-12 months ( either cosmetic or mechanical changes ). This will make the consumers busy updating their models depending upon their buying capacities.
and selling the old models to new consumers with low budgets.
The model thus chosen must have a platform for multiple model production.
I know atleast in India it happens so with almost all the Car, Bike, Tractors, Trucks manufactrurs.
Conceiving, Designing, prototype making, tooling, setting up a plant and marketing an entirely new car is somewhat very difficult if not impossible in view of the very high cost inputs involved.
