Business auto insurance is not always best handled by the same brokers and underwriters that handle personal auto insurance, and it is not advised to insure a business vehicle as if it were for personal use. To get the best business auto insurance quote, start by dealing with the broker who handles your general business insurance needs. In addition, ask the dealer from whom you plan to buy the car if he has any suggestions or if the dealership offers any type of assistance with business auto insurance plans through an affiliated broker.
