I know nearly 10 mechanics in Lahore who are good in fixing Jeeps.
Initially they seems very economical, kay bas yeh wala kaam kerva lain, baki sab theek hey. But once they open/dismantle the mechanical parts, then all their initial economical views takes the u-turn 
Its like 10 years I am fixing my vehicles from Osama and yes he is one window operation for all types of auto works. And at his workshop you can leave your jeep with peace of mind. Either your jeep cost 1 million or 50 million, its totally safe there.
Last week one of my neighbours wanted to has his honda city checked from workshop since it started consuming more fuel. I referred him osama and ask him that he can leave his car to his workshop for couple of days and let him work on it. And his response was hilarious. He said na na na….. I never trust any mechanics/workshops and will NEVER EVER prefer to leave my car there in any case. I smiled and replied ok then you can find another mechanic who may know the Kala Jaddu and fix your car while snapping his fingers
