Collision and comprehensive insurance are two optional types of auto insurance where your insurer pays for repairs to your vehicle. While there are other optional auto insurance coverages, liability, comprehensive, and collision are three of the most common. These coverages work hand-in-hand to repair or replace most of the damages to your car. It's important to know the difference, and make sure you're adequately covered.
Once you know the approximate value of your car and the cost to carry collision coverage, then you can make an informed decision about purchasing that coverage. Many people find that it's a good idea to cover newer cars, but as cars get older, their values decrease, and you might consider omitting or dropping this coverage to save money on your auto insurance.
There are many factors that go into determining your car insurance rates. Some, like your age and gender, are out of your control. Others, like where you live and your marital status, are somewhat in your control. Finally, there are several factors that affect your auto insurance rates, like the insurance company you choose to work with, your driving record, your credit score, the kind of car you drive, and the amount of coverage you choose, that are completely within your control.
