Imagine the stories it could tell!

Classic Design and Distinctive Features
This 1973 Pontiac GTO Sport Coupe truly captures the essence of its era. The body is finished in a rich Burma Brown. It features bold GTO graphics that announce its pedigree. Brown and beige stripes add to its unique visual appeal. The beige vinyl roof provides a sophisticated contrast.
The hood retains its iconic NACA-style ducts. These were originally intended for a Ram Air system. However, the system was canceled before production. As a result, the factory blocked off the ducts, making them nonfunctional. This detail adds to its unique story. Additional exterior highlights include stylish quarter-window louvers. Sport mirror housings enhance its athletic look. Protective body-side moldings add durability. Chrome bumpers with front and rear guards and black rubber strips complete the classic aesthetic.
