Very sorry to hear of John's passing. Like many, I have consulted his auto manuals when working on cars. I used Chilton's as well. I always admired his entrepreneurial endeavors. One of the more interesting things about his series of manuals is the ownership manuals on aircraft, ships and submarines.

Rest in peace John and a big thank you for your help in our automotive restoration and repair projects.
