My dad and I enjoyed the day together doing something we both enjoy – looking at cars and being together. As usual, he took his 1958 Packard Hawk to the Shelby County Applefest in downtown Sidney Ohio on Saturday and wondered if I was going to enter my Mercedes Benz 300D Turbodiesel this year. I laughed at the idea since its my daily driver and not a show car … but after realizing that there wasn’t a single Mercedes in the town or in the fairly large showing … I might consider it next year?
