I bought a yakima saris 2 bike rack today, it fits perfectly and does not interfere with the spoiler up or down. although the yakima catalog says no applications for the xfire, it works perfectly with the addition of yakima's "glass hatchback" special top straps. The actually slide thru the hatchback and have these sort of rubber dumbells about 6 inches long on the inside end so they put the stress on the metal interior of the hatchback and the underside inside of the roof. The other straps side and bottom just go on the lower part of the hatchback. Middle foot sits on the glass (stability and tension only, not weight bearing), bottom feet (weight bearing) on top of the bumper.

Also, it its fairly cool looking and hi tech so it does not look junky. for 160 it shouldnt.
