It seems unbelievable. Even in USA, with all the latest technology of the world, this is not possible in a street garage, done by some mechanics. But if it is real, I have no doubt on the Poor Body fabricators in Pakistan, as they do have God gifted talent, as I have witnessed in many household goods, etc.
Anyhow, hopefully this is something our Auto Assemblers can emulate and learn to fabricate car bodies themselves.
Ferrari and Lamborghinis are also Hand Made in Italy, with skillful laborers taking months to finish the perfect lines.
