I used Tommy Towbar to fit a Westfalia detatchable towbar to my Audi. He was recommended by the trade supplier of my car. Tommy did a first class job. I tow a caravan and he took particular care to ensure that the towbar electrics supplied power to my caravan's fridge while on the road. Tommy himself is very affable, and doesn't mind explaining and demonstrating all aspects of the towbar, how it is fitted to and removed from the car and the electrical connections. Staff are friendly & helpful too. Some time later, through my stupidity, I managed to damage the towbar's electrical socket by moving the car before properly disconnecting the connection cable (common error I'm told). Tommy repaired the socket at no charge. Excellent service. Highly recommended.
