Jeep spare parts are indeed costly. You will find them o-n-l-y at the agents. Couple of years back, a QLer owned one and he had off and on advised others at QL that he bought in his spares through online purchase and had them shipped to Doha. Hence, this may be one of the reasons you don't get to see many Jeeps in Qatar. I do not have much information on Land Rover as to its cost of spares and performance.
