Infringement, the use of car logos on the model infringes on other people's trademark rights, and the simulation of the appearance also infringes. Car models currently sold on the market must be authorized by the car manufacturer before they can be produced and sold.
In addition, the soul of a car model is simulation. If there is no car logo, the appearance will not look like a children's toy. Although it does not infringe, adults will not buy it as a decoration.
