The All-Steel was an automobile produced by the All-Steel Motor Car Co. of St. Louis from 1915 to 1916. Also known as the Alstel, it had a rather conventional 4-cylinder engine, but had a unique narrow platform backbone frame that enclosed the propeller shaft and gearbox. The body, electrically welded, was attached to the frame and rear axle at a mere three points, and as such, the body was easily removed. It cost a mere $465. The company was reorganized as the Macon Motor Car Company in January 1917.
