If you live in an area prone to car theft and vandalism, you'll probably sleep easier with comprehensive coverage at your side. Though car theft numbers have steadily decreased over the last several years in the U.S. — actually dipping below 700,000 reported cases in 2013 for the first time since 1967, and remaining at those levels the years following — the odds are still less than encouraging.
We identified the auto insurance companies with the cheapest rates, but, as with anything, you want to be sure you are getting high quality service from your insurance company. Reliable car insurance companies are critical in ensuring a smooth customer-insurer relationship. There are a few factors we deemed most important to evaluate a company on which affect policy holders' satisfaction, such as, the average shopping experience, customer service, ability to resolve complaints, and quote filing process.

Erie is the cheapest insurance company, and arguably the most reliable insurance company as well. They score points by allowing customers to start their quote online, which we personally found to be a streamlined and fast process. Erie also scored the highest marks from the number of policies they offer. Erie offers pet coverage, free accident forgiveness, free vanishing deductibles, roadside assistance, and many more, essentially giving its customers a degree of flexibility not even found amongst the largest insurers. Customers of Erie may also be eligible for its Rate Lock program. This is a unique program where customers won't see their rates increase except for three reasons: you move to a different area, add or remove someone from your policy, or add or subtract a car. Lastly, despite its smaller size, Erie offers the same types of discounts larger national insurers provide such as bundling, anti-lock brakes, anti-theft, young driver and senior driver among others.
How much you pay for comprehensive insurance coverage is determined differently than for basic coverages like property damage and personal injury liability. With those coverages, the amount of protection you buy dictates the cost. The cost of comprehensive insurance coverage, on the other hand, varies depending on the deductible you select. The higher the deductible, the less you'll spend on your premium — but the more you'll spend out of pocket if you file a claim.

When you purchase comprehensive coverage, you will select a set deductible, which is the amount you pay out of pocket toward a covered claim. Let's say you choose a $500 deductible, and your car is later damaged by hail in a covered claim. If it costs $1,500 to repair your car, you would pay your $500 deductible, and your insurance would pay the remaining $1,000.
