I first met him at a car stereo shop in Stoke in 1995 and didn't know it was him. I had a Corsa GSI at the time and was talking to the alarm installer about an article in CCC about how detuned the GSI motor was when this old grey haired chap came over and joined the conversation and I thought he must have read the same article. Later on the shop owner informed me it was Keith Duckworth!
He was a gentleman and true enthusiast.
