Where Does Your Auto Insurance Dollar Go?

You pay your auto insurance. You have the right amount of coverage. So where does all that money go?

The exact cost you will have to pay for your insurance depends on several factors. One factor is what car you drive.

For example, the Porsche 911 tops the list as the most expensive car to insure. A person could pay $2,943.78 a year . . . and that’s with a clean driving record. The Dodge Caliber is the least expensive car to insure.

Another factor that affects your insurance is where you live. Washington DC has the most expensive insurance cost–$1,140 a year. North Dakota, on the other hand, is home of the least expensive insurance, at a cost of $512 a year.
