If you haven't brought your car for maintenance and they have to work on it and change parts and so on you wont understand if they are good or bad. For my regular services at Dodge; they were also cool with prices around 400-500. But when it comes to maintenance and changing parts conditions are changing. If someone will try to charge you 1600 QAR just for a battery of the car after keeping it at the service almost 4 weeks, you will be annoyed too my friend ;). Hope you wont have to suffer for you car as some of us did.

Edit: BTW I heard that Nissan has good service as well, like some of QLers mentioned Mitsubishi is good.
