Diamond Warranty customers consistently say that Diamond has the most affordable policies. There are other providers that offer better coverage and perhaps better customer service, but Diamond has low prices and stands by their warranties. Make sure you read the fine print of your warranty offer and ask questions before signing up for any auto warranty.
