I wouldn't let State Farm insure my dog house. They have a history (at least in 3 cases with myself and close relatives) of being "like a good neighbor" until you file a claim. If the claim is too high, even if you've never filed a claim in 40+ years (wife's aunt), they'll drop you like a hot potato and make up some lie.
That was for homeowner's insurance. I've been told that their auto insurance is a totally different branch and that they just share a common name but I wouldn't use them again even if they were 1/2 the rate of anyone else.
I now have Fidelity National. Great company to deal with and around $212 every 6 months for my Viper with unlimited miles, full coverage and $500 ded.
