A large part of an insurance premium depends on the type of car you drive. Is it a Corvette? Lamborghini? Maybe a Ferrari? Or perhaps you drive a Chevy Volt? Each car will impact the base cost of your monthly insurance mainly for the replacement value of the vehicle. In fact, some states and auto insurance companies will not cover certain vehicles. Also, high theft risk cars cost more to cover as well. Hummers, for example, are more costly than other SUVs and one of the determining aspects is the Hummer is stolen more often than other models. Either way, your premium may be higher due to one of those situations. Since you probably won't be going out and buying a new car just to lower your auto insurance, it's good to know what else can affect the costs of a new policy.
