Old friend of mine, Karl Haas, was his partner in the race car business. Paul drove, Karl partnered on buying cars and having them built. Karl died a few years ago, he and his wife lived in the priciest of the pricey Chicago suburbs.
The funniest story I read was an interview Newman gave to a car magazine where he was prepping for a race and had his gloves immersed in an ice chest. A fan passed by and commented to friends on the gloves, “that’s why they call him cool hand Luke!” Newman said he was dying of laughter inside but didn’t say anything because the race was about to start.
