I don't know the details of the new owner with his 600. As David says, we know the car quite well - previously owned by a German gentleman with a royal "von" name, and a coin collecter of some considerable note. He also owned a similarly coloured 450SE or SEL, and I wonder if he still has that particular car - it was, in fact, his preference over the 6.9.
Also a very keen Citroen owner, a passion shared by his wife who died probably about five years ago. Most vivacious, and enthusiastic lady, and a number of Club members were able to take part in a run that I organized to the gentleman's property situated on the waters of Gosford. It was a most pleasant and memorable occasion. Regards Styria
