The auto parts market is in full swing: the rise of pure web players, who sell better and cheaper, is overshadowing manufacturers.
In this era of financial scarcity which affects most households, the car spare parts sector is not spared. For lack of budget, motorists postpone certain interventions or, if they have no choice, resort to system D and meet their need for auto parts by their own means, bypassing traditional physical actors. Consequently, the challenges of the auto parts market are evolving.

The car piece by piece
It should be noted, however, that the state of the automotive parts market remains on the surface. It does this using the following two levers:
• more complex services that drive prices up: the development of increasingly efficient on-board technologies, the need for a better qualified workforce, the increasing complexity of repairs;
• Prices of spare parts steadily increasing, particularly with regard to visible parts subject to the manufacturers’ monopoly.
This may explain, on the one hand, this maintenance of the traditional market, and on the other hand, the rise of pure players who are gradually taking the place of official garage owners by positioning themselves on the Internet.
