The biggest downside to Erie is that it is only available in Illinois, Indiana, Maryland, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wisconsin. As well, Erie still relies strongly on its agent network; which isn't always a bad thing. A strong agent network is usually key to ensuring a smooth claims process. If you want to quickly buy car insurance without speaking to anyone though, Erie may not be the company for you. While you can start the process online, you ultimately will have to speak with an agent to finalize your quote. Erie will be ideal for any customers within its market, who do not mind putting in some extra effort to get quality and cheap auto insurance.
