actually something similar has been up in america as well. only over there is illegal and over here its llegal.
i know a guy who used to pick up cars from insurance companies and also snatched cars and then mix the parts around and complete one whole car and sell it. after he was caught , he was jailed for sometime.
but in pakistan its illegal. u can go to shairsha and get a nose or end cut and then just swap the parts to complete one whole car. this is a big business in pakistan the bigger the car the more profit
