Which insurance company offers the best deals for car insurance?

Two key Words: Shop Around. Look in your local phone book and call up a bunch of companies and give them your information such as age, driver license number,year, make, and model of car, zip code of residence, etc. You also might want to go to a broker, which is where I have purchased insurance before. A broker is someone who sells insurance on behalf of a bunch of insurance companies, however they are NOT an insurance company themselves. However you will have to pay what's known as a broker's fee, which is included as part of your down payment. Think of a broker as a "market" for insurance companies.
