What led these otherwise normal citizens to attack the family automobile in such a way? From the moment this particular vehicle was bought, it created problems for its owners. This was especially distressing because the people had wanted the car so badly in the first place. They had saved for five years to buy their dream car, but what they got was a nightmare instead.
