When you're considering a new car make sure to get auto insurance quotes to see if you are willing to pay high premiums for your new ride.
What makes an insurance car expensive? 
The most weighty influence on the level of your premium is your own history as a driver. If you have a history of having accidents, then as you would expect, you are a elevated risk to the insurer and so they will charge you more. Worse, if you have been convicted of a motoring offence such as speeding or driving while under the influence, then your insurance will cost you even extra – especially if your license was suspended.

One of the most crucial factor is what kind of car you are trying to insure. Naturally, cars that are more expensive will cost more to restore, and so the insurance will cost you more too. This is not the whole story though, as other features such as engine size, the availability of cheap replacement parts, and the difficulty of repair will have an cost factor too. Finally, some models of car are well acknowledged for being easier to break into or steal than others – the insurance companies are well aware of this and will adjust their quotes accordingly.
