I know that Mr A Samad is a very experienced person in his field of work. I guess he has spent his entire life as a mechanic. You can see this from the lines on his face if you get to meet him.
From my experience in S Arabia where I was maintaining over 30+ vehicles of different brands at an Italian company, I felt basically all the cars are the same with a small difference here and there. I was maintaining Pajeros also. I had just two garages for carrying out the repairs and maintenance. I found no difference with managing different brands of vehicles at the same garages. As such, from my point of view, if a mechanic is good at a Toyota, he is also good at Mitsubishi.
If you get to meet Mr A Samad, tell him you got his name and contact from QL. He will know that I have recommended you. Tell him you need a good job done at a good price and that you will help him get more customers. Good Luck.
