Car insurance companies classify vehicles into groups. You have probably heard of the 20 group rating
scheme that car insurance is subject to, and car insurance is really no different. Insurers rate each car
with a number, usually
between 1 and 20, with regard to how much of a risk they believe it is. If your car is in a higher group
then it is considered quite risky so will be more expensive to insure, whereas owners of lower group vans
will enjoy cheap
car insurance.
The groups are chosen after examining the historical accident rate with that type of car, as well as the
likely cost of repairing it following an accident. Usually, the larger and heavier the car, the more it is
thought to be harder
to drive and expensive to repair, so car insurance quotes will likely be higher for a large car.
