No company can compare to AAA's insurance rates.  The 10% I saved by being an AAA auto club member didn't save me much on my car insurance, but with AAA it isn't needed. 

I have never filed a claim with them before and that is why I can't comfortably give them 5 stars.  Their customer service rocks, though.  If you find an agent you like, you have direct access to them at any time and you don't have to deal with a different person {that may or may not "know" you} every time you call.
