Sir, I bought Nissan Sunny in May, 2005 and still enjoying this beauty.
This car, undoubtly, has no comparison with any locally assemled cars i.e Civic or Corolla. The looks, comfort and petrol average is also exceptional.
You may simply buy it and and then relax...
I have some contact number of World Automobiles, Karachi;
I pray ALLAH to grant you with such a car that is good for you and your family.
