From your conversation about car it seem you are a guy having a little knoweldge about market
people buy mehran because there isnt alternative available as far as resale and spare are concern

before you buy a car i suggest you do a little macro survey about car , there values there spares there average /mileage
khyber was well built but discontinue after 2000
cultus is good but now out of scope-price.
buying a old car is putting a risk on investment.
buying a new car is wise
