Hi,aj _Gondal ,
here in Qatar no body is allowing to take their vehicle for off-shore driving,(but every bodyTaking 4x4 for offshore Driving).actually their Insurance policy is not llowing to Drive in offshore.it means if some thing happened from the Desert,then you have to Bear the charges,that's it.and if you have enough confident then you may proceed ,no need tell them that where and why you are taking the car.but take care of the vehicle as your own vehicle...
