They came at 9 in the morning to do maintenance for my car, and the maintenance engineer had excellent and fast dealings. But he said, I have to do an examination with 640 riyals, and if the maintenance is settled, they deduct the inspection value from the maintenance amount. However, he says, it is necessary to come at 7 in the morning to check if the car turns out on the same day.
