I'm in the same boat, State Farm constantly increases my car insurance even though nothing has changed and no wrecks, claims...etc. etc. The only thing, I'm nervous about it. Won't other carries look into why you're switching? It just irks me. Yes, I'd like to save some coin, but other than the cost, State Farm has been pretty good. They just replaced my roof and didn't cost me a dime. I also got earthquake insurance...thanks to the fracking going on....as a rider. I've heard that State Farm is the only insurance that offers earthquake insurance as a rider and not having to issue a total different policy. I guess I'm not the well informed consumer on this subject yet.
The price of auto insurance in general has increased a good amount in the last few years. Lower fuel prices=more driving, greater chances for accidents. Higher insurance costs, less people can afford it, they drive around without insurance, and that equals more uninsured motorist claims. The recent hurricanes don't help either. We all pay higher premiums because of this.
