This 1981 Volkswagen Polo 86C Steilheck USA Prototype is an exceptionally rare factory development vehicle finished in blue over a matching blue interior. Powered by a 1.3-liter inline-four paired with a manual transmission, the car shows approximately 1,600 miles and represents what is believed to be a one-of-one prototype developed by Volkswagen AG as part of its research and development program for the American market. It is offered with a recent technical refurbishment and a current MOT valid through February 2028.

Production of the Polo 86C officially began in September 1981, though this example rolled off Volkswagen's Wolfsburg production line on August 3, 1981, giving it an exceptionally early production chassis number of 117. Following assembly, the car was retained by Volkswagen AG's Research and Development Department, where it was converted into a prototype built to evaluate compliance with U.S. market regulations. It was later sold to a Volkswagen employee, who reportedly drove the car for approximately 1,500 miles before it was acquired by the renowned Hermann Walter Museum, where it remained preserved indoors for decades.

This prototype incorporates numerous features unique to its intended American-market specification. Distinguishing equipment includes federally compliant 5-mph impact bumpers, sealed-beam headlights, a unique U.S.-market grille, front running lights, dual reversing lamps, relocated license plate lighting mounted to the tailgate, and an MPH speedometer with an OXS warning light and shift indicator. Under the hood, the engine is equipped with a catalytic converter and additional emissions equipment developed specifically for the American market.

The blue interior remains true to the prototype's original configuration and reflects the car's remarkably low mileage. As expected of a museum-preserved vehicle, it has accumulated a few minor dents, scratches, and isolated areas of superficial surface rust over more than four decades of storage, though these cosmetic imperfections do little to detract from its historical significance.
