I'm looking to buy a set of OEM roof racks for a 2012+ A6. They are the horizontal bars (two of them) that go along the width of the car on the roof. They have to mount without the roof rails - so basically to the upper part of where the door closes with the body.
Those cross bars for a sedan are 4G5-071-126 and the ones right from that Audi acc book are 399.28 dollars. Retail is 460.00 dollars. Plus shipping on these at about 30.00 to a place in WA just over the border for you to pick them up. Up to you but it may make it easier on you to buy from your local dealer and get them faster. Get a break on price by bringing in a 10% off coupon on parts if you have one, or mention you are a quattro club member for a discount? We can ship something of this size to you in Ontario but UPS fees plus the shipping charges, not good, as I'm sure you know.
