No one cares about the country in Pakistan. From average poor people, all the way up to the people in charge. The Indians started designing their own car just in 1998, with Tata Indica being their first ever Modern Indian Car, which was actually not even designed by Indians but Italians, the engine was that Tata Indica was made with Fiat Italian imported Technology, everything was imported in that First Indian Car. Few years later Pakistanis designed their own Car, Revo, in 2005, and launched it, the only thing imported was engine, which was to be Made in Pakistan at a later stage.
An average of 5,000 Car per year needed to be sold, in order to keep the factory open. At first, Shaukat Aziz promised that he will buy few thousand cars for Government departments. But did not honor his pledge, due to unknown reasons. Not only that, but Government of Pakistan also opened import of USED cars, which further damaged the survival rate of a newly made Pakistani Car.
Third factor was lack of interest from Pakistani people. At that time, Pakistanis were paying 3 to 4 lakh for a Mehran, but Revo was launched for an unbelievable price of 2 Lakh, and again Government ruined it further by levying 69,000 Rs tax on it, to make sell for 2.69 Lakh. Which was still a low price for a brand new, and better made car. If Revo had survived they made have offered airbags, anti-lock brakes, etc all under 6 to 7 Lakh which Mehran is looting the customers with.
