The document summarizes the product life cycle of the Hindustan Ambassador car in India. It describes the origins of the car as a license-built version of the Morris Oxford III in 1958. Over several decades and models (Mark I to Mark IV), few changes were made to the car's frame. In later phases (1990s onwards), more changes like new engines and cosmetic updates were introduced in models like the Nova, 1800 ISZ, and Classic. The most radical revision was the Avigo launched in 2004, which had a new design but retained the rear. The Ambassador has been in continuous production since 1958.
