Jeep is very unpopular because of its spare parts being very costly. The spare are available only with the agents. Couple of years' back a QLer who owned one, commented that he bought the spares online and had them shipped to Doha. There are not many Range Rovers seen on Doha roads and the reasons could be several. BMW's are no doubt many to be seen in town but it may that it's regular maintenance my be required to be done at the agents. BMW's have a resale value while the other two don't and you may find it difficult to sell them off.
