Several of the white 1969 Camaro RS/SS 396 convertible NASCAR pace cars were present at the Daytona International Speedway in Daytona Beach, Florida during Speedweeks in February 1969. It seems that they were used in some official capacity at the track in addition to being paraded around prior to the events to promote the upcoming NASCAR events at other race tracks.
In addition to the Daytona 500 Camaro RS/SS 396 convertible on the right, this great picture shows at least four other NASCAR Camaro pace cars. The one in the front is the Camaro RS/SS 396 convertible that would be used to pace the 1969 World 600 NASCAR Grand National event at Charlotte Motor Speedway in Charlotte, North Carolina on Sunday, May 25, 1969. Notice that the Charlotte Camaro has the chrome "dog dish" hub caps as well as chrome trim rings. Unlike the Daytona Camaro, the Charlotte Camaro has a roll bar installed. Color photos show that the side stripe is light blue and black. (stay tuned for a separate thread on this event)
Also notice that not all of the pace cars in the picture are Camaros. Other smaller tracks on the NASCAR circuit employed other makes of cars for their pacing duties.
The picture came from the 2014 auction page of the Daytona Camaro pace car at russoandsteele.com
