State Farm is the only insurance I've ever had in 41 years of driving. We have all our cars, 5er and house there. Over the years I've priced around and haven't been able to beat it. From the perspective of being paid for a claim, I asked my body shop owner one time about the different companies. He said State Farm is the best, they pay what it takes to fix your car correctly, without questions. I asked who was the worst, he said Nationwide. I've had issues being paid by Allstate when the other cars insurance was paying for damage to my car. I've been VERY happy with State Farm, and the way I've been treated.
