I would try the usual suspects like State Farm, AAA, Allstate, and make sure to add in an independent agent or two. With a company like State Farm you are either going to be the perfect canidate and get a great rate or your not a fit and the rate can be extremly high. An independent agent will have access to multiple companies but not the captives like AAA. Let the companies know you are checking their competitors so they will put their best foot forward to win your business. We always encourage our clients to shop our rates expecially when our rates are so hard to beat!
