Allstate has a long history, having offered insurance since 1931, when it began as part of the Sears Roebuck company until it was spun off in 1993. Fun fact, Allstate was a Sear’s tire brand before the name was borrowed for use in selling auto insurance via mail. In 2011, Allstate acquired online focused Esurance to diversify its traditional agent-based sales model. Allstate is headquartered just north of Chicago, Illinois and is the third largest insurance company in the United States with 9.7% market share.
The Car Insurance Guide uses a proprietary algorithm to evaluate the car insurance options presented. Factors reviewed and rated include pricing, handling of claims, age of driver, bundling, and driver type. These factors are evaluated and scored to provide an overall score for the carrier as well as being individually assessed to provide a detailed review of the fit of the carrier to the driver. The data comes from research The Car Insurance Guide conducts as an invite-only annual survey and from interviews with car insurance agents. Insights from experts, those whose job it is to understand and recommend the best insurance companies for their clients, is invaluable. Use of The Car Insurance Guide's 2021 reviews by third parties without the express written consent of The Car Insurance Guide is strictly prohibited.
