In the opening scene, Woody and BJ Long arrive in a 1970 full-sized Pontiac (Catalina or Bonneville) convertible. The car was unmistakable not only for the added bull-horns and other country-bling; the controversial 1970 models were unique, they had the body of the 1960s models but with a stand-up Rolls-Royce-esque grill, similar to what Pontiac would use in the all-new 1971 - 1976 models, in place of the "Pontiac Beak" that had distinguished 1960s Pontiacs through 1969. The 1970 also featured European-looking circular "horn grilles", a feature not seen in Pontiacs before or since.
