Progressive is not high risk auto insurance - it started out that way, but long ago abandoned that strategy. You don't become the third largest auto insurance company sticking with that niche market.
I have Progressive Insurance, and I'm thrilled. I had an accident a month or so ago. I dropped my car off at the service center, they gave me a rental, and that was the last time I saw my car until the work was done. The repair work is guaranteed to be completed by a high quality repair shop. Their claims office is top notch. Price wise, we can never beat them.
