Hi energy:
Here is some info I have gathered about Proficient:
['Proficient', a brainchild of a roadside mechanic, late Khalil-ur-Rahman, in the early eighties was said to be successful but lacked any patronage from any quarter whatsoever and instead it was reported that the government then introduced a policy of concessionary rate on CBU of Suzuki pickups, same capacity as the one that was conceived locally and to put the last nail in the coffin the late mechanic though he would get attention in the capital and thus shifted his garage there but could not succeed. Though the children of the late mechanic are still carrying on their father's projects, they would rather keep a low profile till things finally come out by themselves.]

[A long time ago, a local brand came out, under the brand name Proficient. They mainly competed for the small pickup and medium truck market. Their products were as good as most of the foreign brands, and were cheaper as well. However, because of a lack of cooperation and encouragement from the government, it could not go on for too long.]
