What is the car used in the purge anarchy?

In the movie "The Purge Anarchy" a mother and daughter's car breaks down. They are then rescued by a vindictive man who is out on the night of the Purge so that he can kill murderers, after his son was killed on the Purge Night. To answer your question, the purpose of the car was to transport the mother and daughter from a location to another. For example, from school to home. Another example, from the shopping mall to a restaurant. I hope this was helpful.
