A class is always a singleton. There is only one class named Car in the system. However, there can be many car instances, usually created by sending "new" to "Car".
In the Car class, you'd hold information collectively about all cars, such as the default specifications or number of cars produced.
In each car instance, you'd hold information about a specific car, like its color or owner.
Does that help?
