And buy what instead? rickshaws?
People do NOT buy Mehran out of enthusiasm but for its cheap maintenance and resale.
There are several things that needs to happen before this will change. I can discuss those, and I have in other posts, but it will be too long.
We can all wish for this to happen or that to happen, but real life is more than theories. At least, it requires those theories that can be practical too not just sound good on paper.
So briefly, in my opinion, the real game changer will be when some company decides to bring a bare bone cheap car that can compete with Mehran..without any power steering,windows,etc. And mostly importantly establish good and extensive after sale centers. Get itself established in 4-5 yrs and the competition will automatically start and you will start seeing companies introducing features and marketing them. Currently, few car companies even bother to give an ad.
We haven't so far even restricted ourselves from paying "own" or buying second hand cars at a higher price than new ones.
The second way would be for the rupee to somehow stabilize and give more people purchasing power. That can attract new investors into the automotive sector.
Currently, the sale of passenger cars in Pakistan is roughly 1.25 lacs/yr which is hardly enough to accommodate any new brand, in terms of heavy investment. Setting up a new plant to manufacture, investing in sale/services centers, etc requires huge investment...and what for? for selling maybe 10,000-20,000 cars only(and that too if they are lucky and get extremely positive response)?
