I recently upgraded my 2007 A6 to a 2014 3.0. I have a factory set of roof racks I used just a few time to carry my kayak. They are like new and attach solidly to the roof using out-of-sight holes that are model specific and do not fit the 2014 car. I have purchased a new set for the 2014 and am offering the now unused ones for sale. Factory part number 4FO-071-126 "Base Carrier," list price new was $461.00.
