The Smith family had never owned a car until they bought their first automobile （汽车） in 1906. Before they bought it， they had only used horses for transportation. They had never owned anything so expensive before they bought the car.
The Smith family was very excited about their automobile. The children had never ridden in an automobile before their parents purchased the car. They had only seen a few automobiles when they went to town for supplies. But nobody they knew had ever owned an automobile before that day. They felt very lucky.
How do we use this tense？
