Car insurance comparison sites are probably the easiest way to find great deals. They have direct feeds to many car insurance company quoting systems. Therefore all you need to do is fill in one form and you will get quotes from all the companies the comparison engine affiliates to. Some fo these sites have more insurance providers than others when it comes to quoting. Remember that this is a third party quoting system so the best quote you get with the comparison site may be bettered if you go to the insurance provider themselves.
