A station wagon is a longer stretched car with an added door in the rear. In most cases the rear door is also called the fifth door, hence how the five-door car came to be. Capable of more carrying and storage capacity, the station wagon is ideal for people who tend to need more space in their truck and would rather have a car than a big truck or SUV. The term station wagon is used primarily in North American markets, while other countries refer to the same class as an estate car or estate wagon.
