What exactly does a car dealer do?

Car dealers also sell cars, but there is a difference between car dealers and 4s shops. The car dealership is only responsible for selling cars, and the car dealership does not provide warranty service and maintenance service. If you buy a car in a garage, you have to go to a 4s shop for maintenance, repair and warranty. Many consumers are willing to go to car shops to buy cars, because the prices of some car shops are more advantageous than those of 4s shops.
