Mustang Monthly – December 1992
This is a very good article that not only describes the car but provides details on its background. It gives credit to Joe Laura of the Mustang Business Planning group and even mentions how he spotted them on a then recent vacation.The article also alludes to the 1993 feature cars in two places. In the first reference it mentions a possible yellow car. It also says that the group was toying with the idea of black running horse inserts on the black headrests.
