Our family auto coverage was originally spawned off of the wife's parents' coverage from the 70's. I went to Dave originally to get a cheaper rate. He look a good look at the policy and explained part by part, how poor the coverage was and how little we'd get in case of an accident. Then in a few minutes, he gave me five times the coverage for much cheaper than we were paying for the 1970's policy.
Anytime I've got a question, he's either got the answer or he finds it out and gets back to me quickly.
