Question: The Series Land Rover that was manufactured in Tehran, Iran, was inspired by which US company?
Context: The Range Rover Classic is a 4x4 luxury SUV series built by British car maker Land Rover from 1970 to 1996; until 1978 Land Rover was part of the overall British Leyland group.  The first generation of vehicles produced under the Range Rover name, it debuted as a 2-door model; a 4-door became available in 1981, with the 2-door phased out in January 1994.  For most of its history it was known simply as the "Range Rover"; Land Rover coined the term "Range Rover Classic" to distinguish it from the P38A which succeeded it when the two were briefly built alongside, and applied the name retrospectively to all first-generation Range Rovers. Powertrain Ltd was a British company based in Birmingham which made some cars, manufactured and marketed car engines and transmissions.  The company was owned by MG Rover Group and Phoenix Venture Holdings.  It was based in the South Works at Rover's Longbridge plant.  The companies main products were the K-Series four-cylinder and six-cylinder Engines and the L-Series four-cylinder diesel engine.  The company mainly produced engines for MG Rover between 2000 and 2005 but also supplied Ford Land Rover with the L-Series and K-Series engines for the Land Rover Freelander which was developed by Rover Group in the 1990s during the ownership by BMW and British Aerospace.  As well as Land Rover, K-Series engines were also supplied to many small mass production car companies like MG Rover such as FSO and SAPIA. Morattab is an SUV manufacturer based in Tehran, Iran.  Since 1962, the company has produced versions of the Series Land Rover under license in Iran.  The currently produced models are versions of the "Series IV" made by Santana Motor of Spain until the early 1990s, when the production tooling and design were sold to Morattab and shipped to Iran. The Land Rover Series I, II, and III (commonly referred to as "series" Land Rovers, to distinguish them from later models) are off-road vehicles produced by the British manufacturer Rover Company that were inspired by the US-built Willys Jeep.  In 1992, Land Rover claimed that 70% of all the vehicles they had built were still in use. Rovers North Inc is a privately held Land Rover parts dealer located in Westford, Vermont, United States.

The Land Rover Discovery Sport (codename L550) is a premium compact SUV produced by British manufacturer Land Rover.  It replaces the Land Rover Freelander in a revised Land Rover range of vehicles, with Discovery joining Range Rover as a sub-brand.  The new Discovery sub-brand, to be focused on leisure vehicles, will feature two models initially, the compact Discovery Sport and the larger Discovery (sold as the LR4 in North America). The Land Rover Llama is a vehicle that was designed and developed by the British company Land Rover in the mid-1980s.  11 prototypes and a single production vehicle were built during 1986/7 with the hope of winning a contract from the Ministry of Defence (MoD) to replace its existing fleet of Land Rover 101 gun tractors.  Heavily based on the contemporary Land Rover One Ten, the Llama was intended to be sold on both the military and civilian markets.  However, the MoD did not choose Land Rover's design and without the security of these sales Land Rover was unwilling to risk putting the Llama on the market. The Land Rover Perentie is a nickname for the Land Rover 110 produced by JRA Limited for the Australian Army, and part manufactured and assembled in Moorebank, New South Wales, during the 1980s and 1990s.  There were two build contracts.  The first was in 1988 and the second build quantity occurred in 1998.  The Perentie was based on the Land Rover Defender 110, and was introduced in 1987 to replace the ageing fleet of Series 2A and 3 Land Rovers.  The Land Rover Perenties were produced in 4 x 4 and 6 x 6 variants and powered by an Isuzu 3.9-litre four-cylinder 4BD1 diesel engine or 4BD1-T turbo (see List of Isuzu engines), and has proven itself both in Australia and on operations overseas, including in Somalia, Timor Leste, the Solomon Islands, Iraq and Afghanistan. The Land Rover Defender (initially called the Land Rover Ninety and Land Rover One Ten) is a British four-wheel drive off-road vehicle developed from the original Land Rover Series launched in June 1948.  After a continuous run of 67 years production finally ended on 29 January 2016 when the last Defender, H166 HUE, rolled off the production line at 09:22hrs GMT.

Jaguar Land Rover Automotive PLC is the holding company of Jaguar Land Rover Limited, a British multinational automotive company with its headquarters in Whitley, Coventry, United Kingdom, and a subsidiary of Indian automaker Tata Motors.  The principal activity of Jaguar Land Rover Limited is the design, development, manufacture and sale of vehicles bearing the Jaguar and Land Rover (including Range Rover) marques.  Both marques have long and complex histories prior to their merger, going back to the 1940s, first coming together in 1968 as part of the ill-fated British Leyland conglomerate; and later existed independently of each other as subsidiaries of BMW (in the case of Land Rover), and Ford Motor Company (in the case of Jaguar); Ford later acquired Land Rover from BMW in 2000 following the break-up of the former Rover Group; which was effectively the remainder of British Leyland.
