Roth built the frame himself out of box-shaped steel tubing. The engine came from one of his 1955 Chevrolets. He removed it so that he could put in a newer, larger V8 engine given to him by General Motors. The Orbitron was one of the very few cars which MRoth thought was a "mistake" after he built it. He was very proud of the shiny chrome work he did to the engines and frames of his cars; the Orbitron's engine and frame were covered by the body. The Orbitron was one of his few custom cars to even have a hood. It was said that the automatic hood did not fit well.
