Brother, I only go to FAW motors at Queens Road opposite to Jinnah Degree College near Abid Market. They were official Mitsubishi dealers and mechanics, though are not any more official but they got huge list of Mitsubishi clients so they still entertain them. I am one of them. Though they are little expansive then cheeda meeda gama kala neela peela mechanics yet they are professional and know the stuff. They also got all spare parts for Mitsubishi EK. I got OEM air filter, oil filter, genuine Mitsubishi plugs etc from them. Go to them and take their advice. There is a guy named Zahid and other one is Rashid.
If price suites you get your work done from them, if they seem expensive to you, Go to Magic Motors in model town.
Bro, I love my car so I don't bother much about money to be spent on my car. Thing is quality always cost you more. Rest is your decision.
Jazak Allah, Wassalam
