If ur gonnna buy any of these then think of the following-
Land Cruiser- Too common, resale value
Nissan Safari- Common, resale value
Pajero- Good offroader, But also common, Cheap
Hummer H2 or H3- Burden on the planet. H3 is a Joke , H3 is cheap
Range rover (HSE/Sport/Vogue)- Too expensive, powerful,Getting common
Fortuner / Prado- Sucks offroad, cheap
Mercedes M class- Rare, Fast powerful, very expensive, safe
Kia Sportage/Seranto- Body roll, not safe at all, Dead cheap
Porsche Cayenne Turbo/ S- Its a Porche! Fastest SUV ever, expensive, Boring looks ( cmon for that money you expect it to look stunning)
Jeep Cherokee, Wrangler, Grand Cherokee, Dodge- Maintainence, Cheaper than regular SVUs in its class, Bad Fuel economy, powerful

Best SUV to buy in Doha.
VOLVO XC-90 - SAFE, Nominal fuel consumption, Sold by domasco (honda), 7 seats, powerful, not very common. Value for money

Take my word for it...The Volvo XC 90 is the best one for all the dangerous driving in DOha
