Large insurance companies analyze a huge amount of customers’ personal data, such as social media posts, credit scores, and even your web shopping habits. Then, they churn the data through a proprietary algorithm that estimates how likely you are to shop around or just renew your existing policy each year. By doing so, they can increase your premium just enough to raise their profit margins without attracting your attention and prompting you to shop for a new policy.
Ameriprise was the winner of the J.D. Power study, scoring a 5/5 stars overall. They got top marks in their billing practices and in the flexibility of policies they offer to customers. They had slightly lower marks in their claims handling process (4/5) as well as their agents' interaction with customers. We could not get pricing for Ameriprise but the company is generally known for offering affordable and competitive rates.
As we mention above, Nationwide was the best company in California for cheap car insurance. The large auto insurer even bested typically cheap insurers like GEICO and Progressive. In most cities that we surveyed in the Golden State, Nationwide was the go-to local company for low cost rates. In terms of the company's customer satisfaction however, Nationwide is only mediocre according to the J.D. Power auto insurance study of California. Nationwide scored mostly 3/5 stars in most categories including interaction with agents, and their method of billing. They did score 4/5 stars however when it came to the claims handling process
Once you have a few data points, it is time to pick up the phone and negotiate with representatives. Call them and share the cheaper rates you've gotten from competitors, and 1) see what they do, or 2) follow up with: can you do better than this? Afterwards, ask them for any discounts that aren't available on the website, or what they can offer you from the discounts we've listed below.

The company’s discounts are numerous, varied, and designed to reward you, not just your car. It offers deductions for paying your premium on time, signing up for a policy early, and it even offers discounts for continuous coverage (renewing your policy before it expires). These types of discounts are less common than you might think, and they demonstrate that Travelers doesn’t just want to save money for its new customers — it’s concerned with keeping its old ones happy, too.
Comprehensive covers theft or damage caused by something other than a collision with another car or object. This includes vandalism, natural disasters, and damage caused by animals. If you live in an earthquake-prone region or one with high deer populations, comprehensive coverage will protect against those environmental factors beyond your control.
We first looked for companies that received an "A-" or better (“strong”) from A.M. Best, a rating agency specifically focused on the insurance industry. Then, because the III recommends getting ratings from more than one agency, the best needed to earn at least an "AA-" (“very strong”) from S&P Global or an "Aa3" (“excellent”) or higher from Moody’s.
Many insurers state that their policies offer ‘full coverage’ without detailing what that means, because, well, it doesn’t really mean anything. According to Jonathan O’Steen, personal injury attorney and partner at O’Steen & Harrison LLC, “Some insurance agents use ‘full coverage’ as a shorthand way to describe auto policies that only meet state minimum limits for coverage. True full coverage would provide unlimited protection for all losses arising from an automobile accident.”
If you have an anti-theft device, Progressive offers a discount for that too. The company also offers pet injury coverage — which is included with collision and comes standard in most states. However, Progressive’s scores across the board were only average, and we couldn’t justify recommending it over our top picks. Also, its mobile app ratings average out to just under 3 out of 5 stars.
Within L.A. county rates can change dramatically. Even jumping one or two zip codes over within Los Angeles can make a difference for Angelenos. Moving the primary garage or parking spot from Long Beach to Walnut, for example, can reduce annual car insurance premiums by $259 for a 30 year old male. Overall the average rate of L.A. county is $1,780, with 25% of cities having rates under $1,700 for our sample driver. Overall, Walnut is the cheapest at $1,483 and Los Angeles proper the most expensive at $2,257.
