Although it's cheaper to have third party fire and theft, if you drive a more expensive car make a comprehensive policy may offer more protection for any damage to your vehicle. Many companies do not allow third party insurance for cars over a specific value for your protection.
In some cases if you add a second driver it can cost you more, especially if that driver is young or has a bad driving record. There are many policies, where if the driver you are adding has as good of record as you, may not cost you anymore.
One way to get lower car insurance is to buy a car that belongs to one of the lower insurance groups. These are norammly vehicles with a lower engine size and basic equipment and cheaper to repair in the case of an accident.
