I have dealt with the dealer of Porsche in Oman however, am completely not satisfied with the service for several reasons: 1. The price of a normal maintinance is very high comparing to others for just changing the oil and filter they charge over 120 USD 2. No check on the car is bein done 3. The parts I buy overseas is away less expensive than getting it from the dealer 4. They do slappy job when it comes to repairing or replacing a part, they cause other problems with other parts and again I need to pay for new parts( am just affraid taking my car to the dealer so I dont get ripped off) 5. when the prices are discussed they always tell me to not worry and when I see the bill I get disappointed. 6. they charges for replacing the part but they just fix it and put it back if you dont notice 7. I had a problem with the RPM meter when I asked them to check they answered dont worry you go and nothing seriouse will happen to the car.so reliefing!!!
