I will now be paying $1400 a year, for two vehicles with Mercury. you can go to Mercury's website and get an automated quote.
in the LA area, Mercury and AAA are the cheapest, and are both really good from my experience.
I know that state farm, all state, 21st century are all fantastic as well.
Geico is a rip off and Progressive, from what i remember, was even worse.
dont forget, if you go through a broker, most of them slap a commission on top of the policy. Some barely sqeeze a little extra while others charge a lot. they just hide in the overall quote.
ps if you dont own a home, get the lowest coverages possible. it makes a big difference in how much you will pay.
