California car insurance company

Reader question:
I heard about buying car insurance rates is a way to get car insurance rates. I am from California and honestly believe that I am paying too much in my car insurance premiums. I think that it is time to switch to another insurer, so I can save my premiums. I need help. How can compare insurance vehicle in California?
