A car model is like a toy car that comes in different colors and styles.
Imagine you have a toy car that looks like a race car, and your friend has the same toy car but it looks like a police car. These are two different models of the same toy car.
Similarly, car manufacturers make different models of cars that have different designs, features, and colors. For example, a Honda Civic and a Toyota Corolla are both models of cars made by different companies. They may look different and have different features like the color, size, and type of engine.
Just like how you can choose what color and style of toy car you want to play with, people can choose what model of car they want to buy based on what they like, need, and can afford.
