Typically, a car model will last around 10 years before it is phased out and replaced by a new model. However, this can vary depending on the make and model of the car. For example, some models may only last for a few years before they are replaced, while others may continue to be produced for many years. There are also some models that are still in production even after several decades. Ultimately, it depends on the popularity of the model and the demand for it.
