The role of car insurance groups

Car insurance groups have evolved dramatically since they first appeared. Originally, the groups were an internal thing for insurance companies to work out the risk of your car, but once they became public knowledge, they also became a sales point for the cars. Even then, they can be something of a mystery, particularly as some insurers still use their own internal grouping system.

Why you should know what insurance group your car is in

Your car’s insurance group can affect the amount of money you have to spend on your car insurance policy; so it is definitely worth knowing which insurance group your car sits in and which groups are cheapest to insure.
