The best-selling car in the UK in 1978 was the Ford Cortina, with over 200,000 units sold. It was a mid-sized family car that was first introduced in 1962 and went through several generations. The Cortina was popular for its reliability, affordability, and spacious interior.
The Cortina’s success was due in part to its wide range of trim levels and engine options, which allowed buyers to choose a car that met their specific needs and budget. It was also available in a variety of body styles, including a saloon, estate, and convertible. The Cortina was a popular choice for families and fleet buyers alike.
