The latest issue of Golf magazine has a back-page interview with Sir Jackie where he states that the fastest he ever drove a car was 242 mph in a GT40.
Ford has a design center in Irvine, California. On Saturday mornings there there used to a loosely organized, ad-hoc car show called “Cars and Coffee” in the parking lot of the Design Center. Everything from exotics, to race cars, to muscle cars. It was free and open to anyone who wanted to show their ride for a few hours on Saturday morning.
I’ll never forget one time I went. There was an original Ford GT40 with a “Gurney Bubble” in the roof (added by Ford so that the car could be driven by Dan Gurney who was quite tall.) that the owner had on display. Well ... guess who was at the car show and standing next to the GT40 (admiring the car with the rest of us?) ..... the MAN himself .... Dan Gurney! I’ve got a picture of it somewhere.
