A lot goes into an auto insurance rate quote, including your ZIP code, coverage levels, marital status, annual mileage, driving history and vehicle make, year and model. In most states, your gender and credit history are also used to determine rates. And again, the reason auto insurance comparison shopping is so important is because rates between companies are different for each person, too.
The main difference between collision and comprehensive coverage comes down to the question of what the driver controls. Collision insurance will cover events within a motorist's control or when another vehicle collides with your car. Comprehensive coverage generally falls under "acts of God or nature," or things that are typically out of your control when driving. These can include events such as a spooked deer, a heavy hailstorm, or a carjacking.
You can also save on car insurance by choosing the lowest amount of coverage you can get while still making sure that you’re meeting your state’s legal requirements for insurance and giving yourself the coverage you need if you’re in an accident. For example, let’s say you choose to get the legal minimum for liability coverage, which we’ll say is $30,000 for this example. If you are at fault for an accident that hurts someone, resulting in $100,000 in medical costs for them, you will be on the hook for the $70,000 difference between your insurance coverage and the harm you caused. You can be sued and lose assets, like your home or retirement savings, if this happens – so make sure you have enough insurance to keep your assets in the event of an accident where you are at fault.
There is a case to be made for getting just comprehensive and not collision insurance, even if your car is not valuable. Comprehensive covers you for a lot more perils than does collision--including, most importantly, against theft. Regardless of the value of your car, having it stolen is a major inconvenience. Even if your car is worth only $2,000 at the time of the theft, and your insurer gives you $1,500, that sum would go a long way in buying yourself a new vehicle. As we discuss in more detail below, comprehensive insurance generally costs no more than $200 per year, so a $1,500 reimbursement would make the coverage valuable.

Collision coverage is limited to the actual cash value of the vehicle, and requires a deductible, which is the amount you'll need to pay before receiving benefits. Higher deductibles lower your premium but increase the amount you must pay out of your own pocket if a loss occurs. Ask yourself how much you would be willing to pay on short notice in order to save on your premium, or talk to your agent.
USAA: USAA is the best car insurance company we found. Customers report that they love USAA for its customer service, ease of filing a claim, and frequent updates on claim status. USAA customers also report that USAA is a good value, and USAA’s average annual rates are some of the lowest in the business. The only downside we could find to USAA is that its insurance products are only available to veterans, members of the military, and their immediate families, so not everyone will be able to work with the top-ranked insurance company.
We surveyed 2,799 consumers who filed a car insurance claim in the last five years, asking questions about their car insurance company. These questions covered satisfaction with the ease of filing a claim, customer service, claim status communication, claim resolution, and overall value. We also asked whether they’d recommend the company and if they planned to renew their policy. We used their responses to build our Best Car Insurance Companies ranking.
Shopping for auto insurance is a very personalized experience; car insurance companies will consider your driving history, credit score, age and more when generating your quote. Some things to consider when shopping for auto insurance are relevant discounts, the claims process, and the coverage you want in addition to your state’s minimum required coverage. Use this guide to compare the top car insurance companies and find the best rates available.
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.

That said, the State Farm quotes we received were shockingly expensive when compared to the competition — typically around three times as much. While the extra cost may be worth the guarantee of good financial strength and customer service, we always recommend gathering quotes from multiple providers to see which strikes the best balance between cost and coverage.
Comprehensive car insurance covers damage to your car if it collides with something other than another car, like an animal or a tree, or if it’s damaged by vandalism, theft, or natural disaster. Again, if you lease your car or have an outstanding loan on it, this type of coverage will be required, but if you pay your car off, or it becomes worth less money than it would cost to repair, you can decline this coverage.

Each insurance company evaluates personal factors in its own way, and they keep their methods as hidden as possible. So we can’t tell you which company puts high value in your occupation or emphasizes a clean driving history more than others. But to help you get going, we can show you a car insurance rate comparison for the same hypothetical driver and car, using average rates from across the country.
