An improved motor vehicle turntable is provided that may be installed in any location, typically in front of a garage for the purpose of rotating a vehicle so as to enable it to leave the area in the opposite direction from which it entered the garage. The motor vehicle turntable has a circular vehicle receiving platform supported by a polygonal support frame. The receiving platform and support frame are received within a cylindrical pit so that the upper surface of the platform is level with the surrounding terrain into which the pit is formed. A chain drive frictionally engages the perimeter of the polygonal support frame to rotate the receiving platform when the chain is moved by means of a drive motor and sprocket arrangement. The drive motor and sprocket arrangement provide a spring biasing to the chain to frictionally engage the perimeter of the support frame under normal operating conditions, but which permits loosening of the chain to manually rotate the receiving platform and support frame if there is a power outage or equipment malfunction.
