Kamran,
VW Pakistan started off in 1954 and finished in 1975. The head office used to be at Port Qasim Karachi and there were several showrooms (official dealers)in the city, as well as Lahore, Peshawar and one branch office in Pindi.
There are no official VW dealers in Pak. The VWs you see are all in private showrooms and hence you will have to come and see for yourself. Karmanns are few and far between though.
