@usman_khawaja,
Good question. I have a reason for that. I guess, in Rwp/Isb, mostly people are of salaried class and they turn happy whenever they see some chance of earning from any mean other than that, either its a car or a plot. Even people here do argue a lot even for 2/3 thousands @ 5 lac amount bargains. So, these all are small businesses for them. I apologise, if someone disagrees, as this is just my guess....which may be wrong.
But in Sialkot, most people are business oriented; agian we are talking about majority, its an industrial city. So, people have business in their day to day activities and they don't believe on focusing other small businesses like this car sale. And they are already earning big.....
