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.

Land Rover Llama: 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.
