Dick.....You don't say what insurance you currently have, but many of us with no claims or changes would suddenly get a huge increase from Progressive in year 4-5. I had a friend once tell me that an insurance will never show loyalty to you, so never worry about showing loyalty to them.
The minute Progressive sent me the dramatically increased premium for no reason, I switched to AAA and got the same coverage for several hundred dollars less than Progressive before their rate increase.
The point.....shop around and don't worry about dumping an insurance company.
