Bhai if the vehicle is in quetta why are you looking for debters, painters and mechanics and parts in Karachi.
You are basically in a city where half the parts for such cars are thrown away. If you want to restore it buy an NCP Range Rover you will have to search for the car but it will be available and scrap it out for parts.
A couple of my friends from quetta suggest that there are debters in area who will join to half cars and a common person won't even notice...
