Just had this email from Watling Engineers.
The bit I'm worried about is cutting the bumper and getting a cover to go in it's place.
Sorry if this has been covered before..............
Dear Mr. Plummer
Thank you for your enquiry for a towing bracket for your BMW M5 E34.
The prices are as follows:-

Unfortunately the towing bracket is not in stock but if you place your order we should dispatch in 7-10 days.
I have never seen a towbar for this vehicle which does not involve a cut to the bumper.
The above towbar is a swan-neck detachable but requires a rectangular cut in the bumper there is a cover provided but it only fits the standard bumper not the shape of the M5 bumper.
