I have just bought new mazda 3 and I have done 1000 KM maintenance in a maintenance center located at Nasr City. I need to know the best center to make the maintenance as I did not trust that center as they do lots of brands maintenance. Do you know a trusted center that is specialized in mazda. I knew that Mansour center at Heliopolis are doing it but they refused to make my car as they do only cars bought from Sonesta. Pls any recommendations.
