"My mother (74) got a renewal letter from her insurance company for her car insurance, wanting $570. After reading
your article on car insurance, I contacted one of the companies you recommended, who quoted her $318 for the same
level of cover. I just wanted to stay thank you very much for your article, as it has saved my mother a substantial amount of money".
