I agree. If you are not in Karachi then why buy a Karachi registered car for the same amount, or even more, that it would cost to buy the registered car of the city which you are in.
Karachi Registered cars are not easy to sell as you yourself would not prefer to buy a Karachi Registered Car until it costs less. The same thing when selling if you sell it for a less amount it would sell otherwise problem in selling
