I switched to Markel because it was almost 1/2 the price of my previous insurer Farm Bureau. I used identical numbers so I was comparing "apples to apples" and went back to my Farm Bureau agent with the numbers. He told me that their higher premiums were no surprise, and I could likely find cheaper rates for the same coverage anywhere.
Other than making my first annual premium and getting my proof of insurance and other documentation in an hour or so, I've had no contact with Markel. Hopefully things stay that way.
