When it comes to buying a new or used car, many people overlook insurance expense as part of the total cost of owning a vehicle. It's better to consider the cost of insurance before you buy since auto insurance premiums vary widely depending on a vehicle's specific characteristics, including its price, average repair costs, safety record and whether or not it's a target among thieves.

Many insurance companies offer multi-policy discounts, such as buying a homeowners policy and auto coverage from the same carrier. You might also be able to save money if you insure all of the vehicles in your household on one policy or if you insure all of your driving-age family members on the same plan. Be sure to do your homework though, since there's a chance you could save more money buying policies from multiple carriers.

Because auto insurance companies and rates vary widely, it helps to shop around when selecting an insurer. As a general rule, it's wise to obtain auto insurance quotes and information from at least three separate companies. Calling insurance carriers directly, asking family and friends about their insurance providers and getting an auto insurance quote online are just some of the steps you can take in helping to ensure you choose the right auto insurance company.
