We ordered the wrong roof rack for our model so it's just been sitting. Service guy realized this as soon as he looked at the box so all parts are practically untouched. Located in Philadelphia. Available for pick up or willing to ship (within reason). This retails at $550 on the website. $475 is the non-negotiable offer.
