Ok before you all go on I know its not the done thing, but I really need a towbar for my Sportback. Ideally I want one that the tow ball can be detached. I saw it in the options list and it was £500 + from Audi so thought I would get one from "somewhere" later. Trouble is no one seems to list the Sportback only the "normal" A3. Anybody got one or know of any supplier? Oh and its to tow the trailer with my racing kart on, not a caravan I promise you!
