I recently bought my 08 used, and will transfer a Yakima setup from my previous car to the XB. A basic system only consists of the two 58" horizontal bars, uprights called Q Towers, and the specialized clips which hook onto the car called Q Clips. 700 bucks is really steep, so maybe you were pricing additional stuff. I haven't installed them yet due to the weather in these parts. This is the kind of rack which is quickly removable, unlike the top example in the above mentioned link. I used this setup a great deal on my previous car, and am very impressed with its strength and versatility. The XB is a great car for these kind of racks, since the bars can be placed very far apart for a nice stable load.
