Hummer has stopped its civil vehicle manufacturing, and now they are manufacturing only military vehicles (by living in U.S. u should have informed us), and if u insist on it u can get used H1, H2 or H3 from the local market of Qatar
in general it is not suitable for this country coz few mechanic now how to repair it and the parts and very expensive.
locals here prefer Land Cruiser and when u will arrive here it will be the first thing that u will notice (land cruisers everywhere)
