I had Allstate for over 20 years and it just kept going up. I would contact my agent to see if anything could be saved and they would adjust it slightly each year, but it was over $200 per month and I had a perfect driving record, and my vehicles were getting older and older. Finally I was fed up and got quotes from nearly a dozen insurers and Esurance beat them all, lowering my payments by more than HALF! Now I'm worried, though, since Allstate has now purchased Esurance. Will my rates start to go up and up again? Time will tell.
Being in the business for a very long time, I have found that most people are clueless about insurance, even most agents who sell them. I will agree that their rates are cheap. But I wouldn’t recommend them. Inexperienced adjusters. They do not fully investigate. The policy does not cover like, kind, and quality which is bad if you have a new vehicle.
