I trust the people who work at Arizona Auto and Radiator. A few years ago, they sold a car for us. They told us they expected to sell it for $4,000; we thought that would be a good price to get for the car. They sold it for $5,000 and gave us the extra $1,000. We would never have known that they sold it for a higher price and would have been happy to receive the $4,000 originally estimated. I don't think that level of honesty is common in many businesses.
