There are dozens of car insurance companies out there who would love to have your business, and although coverage amounts, limits, and other benefits may be similar between the various car insurance carriers in your area, it pays to shop around. Independent Studies have shown that the average consumer may be able to save nearly $500 every 6 months by shopping for the best rate before purchasing a car insurance policy.
