Immediately, Lord Stokes instigated plans to design and introduce new models quickly. The first result of this crash programme was the Morris Marina in early-1971. It used parts from various BL models with new bodywork to produce BL's mass-market competitor. It was one of the strongest-selling cars in the United Kingdom during the 1970s; being the second-most popular new car sold in Britain in 1973. Although by the end of production in 1980 it was widely regarded as a dismal product that had damaged the company's reputation. The Austin Allegro (replacement for the 1100/1300 ranges), launched in 1973, earned a similarly unwanted reputation over its ten-year production life.
