That white MK2 parked behind the triangular PSO fuel station was a piece of trash, it was rusted to hell everywhere, (If you saw some other car then please do post) there was one white mk2 on a sukkur registration number which I bought for myself but sold it out later (before I left pk) - my own is with my uncle.
the member charged here on PW is a VW Golf mk2 owner and can help you source one.
I do know of one mk1 Golf diesel in Karachi in very good condition but the owners are part insane part crazy - its a very low mile example and was actually imported as a brand new car in Pakistan. (the story keeps on changing from dada ki nishaani to ghar ki fard to some other useless crap, the car is not a rotting hulk but its actually taken care of)
