On Friday, January 31, 1969 a white 1969 Camaro RS/SS 396 convertible was used as the pace car for the 250 Mile World Championship Formula Vee race held at Daytona International Speedway in Daytona Beach, Florida. This is the same car with the yellow side stripes that would pace the 24 hour race the next day.
