Americans with small families own a car. If both parents are working , they usually have two cars. When the family is larger, they will sell one of the cars and buy a van(住房汽车).

  A small car can hold four persons and a large car can hold six persons but it is very crowded. A van can hold seven persons easily, so a family with three children can ask their grandparents to go on a holiday travel. They can all travel together.
