Working with an auto insurance broker is a bit different than working with an auto insurance agent. An agent works for the insurance company. As such, you call them up and ask for a quote and they provide you with quotes based on the insurance plans they provide. An auto insurance broker does not work for an insurance company; they work for you. They do the work of finding you the best auto insurance policy for your needs at the best price.
If you are in the market for auto insurance, then you need to make sure that your ducks are in a row. There are many different factors that are going to be used to calculate what you are going to be charged for auto insurance, and some of them are actually in your control. If you are able to get some of these factors under control, then you may find yourself saving money on your car insurance.
