My granddad constantly hounded my dad in the 70s for buying and owning the Road Runner that now sits in my garage. He wanted my dad to get rid of it for being too much of a fun thing (he's an old-school workaholic German). My dad didn't listen to him. Now that my dad is gone, my granddad has a much different view of the car. He asks about it sometimes and tells me how he likes to talk to his friends about the Runner. It's one of the few tangible items that was truly and solely my dad's.
As a side note, my granddad is 90 years old and sharp as a tack. He gets out of bed every day and takes care of all his affairs. His house is as clean as General Patton's barracks and he still drives every other day. After 500 years of history and family lineage, he and I are the last two with our last name. Kinda weird to think about...
