No, there are no official car insurance company rankings. However, if you search the Internet, you will be able to find several reviews on most of the major insurance companies. These reviews usually offer a star rating. Several review websites will allow you to sort the companies from those with the most stars, down to those with the least stars. There are also some independent ranking lists that can be found on the Internet written by companies and individuals. Many of these ranking lists have insurance companies listed similarly. With a little bit of research, you could compile your own comprehensive rankings list based on the qualities you find favorable in an insurance company.
