While State Farm's shopping experience is well-reviewed, customers did not feel as strongly about it's claims handling process. The company scored about the same as the other four large companies, but was still mediocre. A large national company may be expected to not be very efficient because of the various departments involved in handling individual claims. If you want the assurances guaranteed to you by a large, "legacy" carrier, then State Farm is the best to go with.
Insurance companies in the U.S. are an outgrowth of mutual aid societies. Prior to insurance companies (and cars, for that matter) community members would band together, often based on religious or ethnic affiliation, to provide funds in case of an emergency. Each member of a mutual aid society would pay a small amount into a fund that members could draw on in case of certain events, like a death in the family. The money the members pulled out of the fund could be used for things like burial expenses – and because everyone paid a little bit, no one person or family had to bear the full cost of an emergency when one struck.
Results: After working my way through the DMV.org quoting process, I discovered that they don’t actually provide car insurance quotes. Instead, they just provide you with links to other websites where you can get a quote. In my case, it gave me exactly two links: to Esurance and Allstate. Clicking a link to go to one of these websites required me to start all over with the quoting process, leaving me wondering why I’d bothered with DMV.org in the first place.
