My friend rececently bought Mehran with FF CNG and AC. He told me after registration, Sound System (ordinary), Seat covers etc. the car costed him Rs. 440,000/- (incl. Own money).
I would reccomend instead of Mehran u buy 2nd hand Santro 2004 model which will cost the about same price.
You will get benefit of FF Audio System (4-way speaker)
Chilling A/c Performance
No engine heat up, extremely rare engine problem. Superb pick even with AC. Fit for long drive due to better road grip. Better finishing etc..
