From Debbie Dannenfelzer FB page:
It is with a heavy heart that I have to post that Dave Casteel passed last night. Davey was a long time partner and co driver with George Fields of the 125 coupe, affectionately known as “The World’s Tallest Coupe”. You might not have known him well, he was a very quiet person, but he was a good man and a friend. He will be missed. Our hearts go out to his family and long time friend and racing partner George. God Speed old friend.
