The Peugeot 104, presented in 1972, underwent various evolutions over the years. In August 1976 the sedans became 5-door, with the adoption of a tailgate and folding rear seats. In September of the same year changes were introduced in the versions: from the 1977 thousandth the L became GL, with a 44.5hp petrol engine. Some improvements to the braking system and some accessories were also developed.
