Serial production of the VAZ-2104 car was launched at the Volga Automobile Plant in 1984. The new model was produced in parallel with the VAZ-2102 car of the same class until 1985. When creating this model, the designers were guided by an important feature of that time - the creation of a new model with minimal production costs and maximum consumer effect. Therefore, the VAZ-2105 model was taken as the basis. After lengthening the roof, stampings appeared to increase rigidity. This body structure made it possible to place a long trunk on the roof, which was not recommended to be overloaded, since the calculated stiffness of the station wagon body is much lower than that of the sedan.
