how about airbags ?
if airbags were not deployed make list of items you need visit quetta buy parts get those delivered to karachi -
any reasonable denter can do the replacement work and surgically restore the left collar bone. once the denting is completed and car is road worthy again paint work is like walk in park.
most important is sourcing the parts replacement & surgical restoration can be done with ease.
if you can visit the area opposite the Karachi central jail - there is a denter by name of Feroz - due to jammers in area cell phone do not work, you have to pay a visit very easy to access coming from shaheed millat road bridge land at jail gate proceed straight slowly keep on left at the 2nd gate on right stop and look at left thats the shop under tree. name is feroz old man with glasses & a stick in hand.
be nice polite show him the picture of car as posted here and ask if he can help you if he agrees, offer him ride to & from his workshop with fees for car inspection at your place so he can make list of body parts needed and you can source the same.
if he agrees to fix it, rest assured you will not regret money spent for restoration.
Feroz is polite kind hard working man unless annoyed by lose talk and showing power muscle.
( several muscular people visit him quietly in plain clothes sip tea under tree with him for their family cars if & when damaged and agree to his tantrums ... obviously you will not mention this ... it is just to let you know he is no person to be muscled with, if he says no, smile and accept it )
