It happens differently on this service. The owner performs high-quality work, mercenaries- not always. The administrator is smart, the time is selected adaptively.
Everyone hears that the nozzle does not work in my car - for some reason the master does not hear. I had to look for another workshop where they heard. Prior to this case, I was dealing with another problem- they could not adjust the idle speed, I came to them 6 times, and they did not set it up. Where is their skill? And they took the money in full - 800 rubles!
