by the looks of the blind tail lights, it may have been driven by "fast and furious" driver - the black tail lamps adds to their respect.
The roof is buckled in, dont get it hammered or welded, it would be ideal if your denter can graft another roof panel on it, but the car needs a chassis alignment jig to be stretched back in shape. (but that is my opinion only). The doors can be bought as complete assemblies and just bolted on. The major expense here would be the straightening of the car with minimum compromise to strength.
there are a lot of welded POS running in Pakistan so a hammed up job on this car wont make a difference.
