Its funny most the people here seem to jump on the mainstream well advertised carriers... yet when in all reality there are better carriers.
I personally say Auto Owners. #1 for claims service for years, nationwide. Check JD Power, Auto Body Collision poles, etc.
Also this all depends on where you are. Insurance is not the same across the country, city , state, etc. Then take into account variables etc like your personal history, driving record, car, etc.
The best bet is to call a local independant agent or agency. One that can shop around for you. Let them get you the best rate they can, and then if you feel ambitious check a few places yourself.
The rates we give for Progressive are the same you get calling direct. Yet you have an agent and agency that can fight for you in the chance of a claim, etc you are not happy with. When your direct you can get screwed.
Also home is going to give you a discount, and sometimes even picking up a small life policy say $10,000 will actually reduce your house and car payment, more than it costs. Believe that.
What state are you in?
Good luck.
