Frontispiece: There is no doubt to the 1973 GTO’s rarity. Still, on occasion, you might end up seeing three at the same time. (Photo Courtesy Bill Markowski)
Title Page: Clever advertising slogans were plentiful with The Judge package. One such GM ad stated, “The Judge can be bought.”
Back Cover Photos
Right: The year 1970 remains the zenith of muscle car production and the 1970 GTO The Judge remains a crucial component of that claim. (Photo Courtesy Bill Markowski)
Left: The 1974 GTO, given the economic times of 1973–1974, was able to beat the 1973 GTO in terms of sales. Dual exhausts and a functional hood scoop were part of that success. (Photo Courtesy Bill Markowski)
