Sold my A4 and I no longer have a use for the roof rack (base carrier) cross bars. They’ve only been used a handful of times and are in perfect working condition. Comes with 2 keys and the torque wrench to tighten them onto the roof. Retail is $440 and I’m asking for $300 plus shipping (which I’m not sure of the cost yet). Located in Southern California.
