Hummer belongs to General Motors. At present, it produces H 1, H 1 civil vehicles, H2 and H3. Among them, H 1 is a high-mobility and high-performance all-terrain vehicle. The American Gulf War shines brilliantly. Belongs to all-terrain vehicles. The military expenditure is about10-200,000 dollars. H2 and H3 belong to small civil buildings with good comfort. But the passability is far from H 1.

Land Rover, formerly known as Land Rover, originated in Britain, but was sold to Ford due to poor quality and poor sales. After Ford took over, the quality was still very poor and the benefits were also very poor. Recently sold to India's Tata Company. Although he is a pioneer in cross-country, his quality is really not flattering and his technology is not advanced. Last year, it was rated as the last one in the United States, which shows how poor the quality is.

Jeep belongs to Chrysler Company, and its predecessor AMC American Automobile Company cooperated with Beijing to produce Cherokee 2 13, which became famous in World War II. It can be said that it is the originator of off-road vehicles (a bit boastful), with average quality, high fuel consumption and not advanced technology. There are mainly Grand Cherokee, Liberty, Patriot and other models. Sales are flat. The main reason is that the quality is not up to standard.
