We can retrofit a high quality detachable Towbar manufactured by Westfalia (They make towbars directly for Mercedes). This is discreetly mounted within the rear bumper itself and when removed is virtually invisible. The detachable part is then stored in its own carrier under the boot floor. A 13 pin electrics connection is mounted on a hinged bracket to allow simple connection when needed and completely discreet when not. Electrics are fully compliant with the complex circuitry of the car as we use dedicated electrics kit specifically made for this vehicle.
Full 13 pin connectivity allows for use with caravans as well as trailers. (older style 7 pin electrics also available)
