If you're looking to buy a new car, one of the things you should do is check out how much your insurance will change based on the new make and model you choose. While there are many factors that influence the price you'll pay for insurance, the vehicle you drive is an important one. Pick a sports car like the Corvette, which ranks number 5 most expensive to insure, and you'll pay much more than if you had chosen to drive a Kia Sedona, which is the cheapest car to insure.

The list of the most expensive cars to insure and the cheapest cars to insure in 2010 comes from InsWeb, which compared insurance rate requests from customers for over 400 models from January to September of this year.

When you go looking for a vehicle, keep in mind that the performance cars which dominate on the speedway also dominate on the most expensive to insure list. This is because drivers of these sports cars are more likely to engage in speeding and risky behavior, than say a family cruising along the interstate in a small SUV. The value of a car and repair costs are also a huge factor, since a crash in a $50,000 Acura ZDX will cost more to repair than a $25,000 Kia Sedona.

Figuring out how much it would cost you to insure a car is a simple process these days that should only take a few minutes. If you have a local agent you can give them a call, and tell them a few different models you are looking at purchasing. Or if you are looking for new insurance you can get free quotes online from companies like InsWeb and others who will check the rates at numerous insurance providers to help you compare prices -- and the difference between what you currently pay.

While there are a variety of factors that play into how much you will pay for car insurance, Brad Cooper, Senior Vice President at InsWeb, told WalletPop in a phone interview that drivers should make sure their "personal profile" is up to date to ensure they are getting the best rates.

For example, recently unemployed drivers may now drive much less, which could reduce the cost of insuring their car at a time when it is most needed. Because there are many factors at play, Cooper suggests taking time to talk to your agent or insurance representative every six to 12 months to ensure that you are getting the best price and the right amount of coverage.
