There are three cars in total. The first one is a sedan, which is a four-door car with a trunk. It's usually used by families or business people for daily transportation. The second one is an SUV, which stands for Sports Utility Vehicle and has higher ground clearance than other cars. It can be used for off-road driving and towing. The third one is a hatchback, which has two or three doors and a rear hatch that opens up into the cargo area. It's usually smaller than sedans and great for city driving due to its compact size.
