1979 El Camino

(Chevrolet photo)
In the foreground is a Royal Knight edition El Camino SS. It is hard not to notice the "Trans Am - ish" graphics. In the background is a Conquista model which features separate roof and lower body colors. The GMC Caballero had a similar Conquista trim option called the "Laredo". The GMC equivalent to the Royal Knight was the "Diablo".
