This three-bike trunk-mount bike carrier was lightly used and is in like-new condition. The model is Thule 515-5001-02. The current Thule version of this model appears to be the Thule Passage, which retails for $150: http://www.thule.com/en-us/us/products/carriers-and-racks/bike-carriers/rear-door-mounted-bike-carriers/thule-passage-3-bike-911xt-_-4806509
Thule describes the carrier as having soft rubber cradles which protect the bike frame while holding it securely, provides the perfect fit to your vehicle, arms fold down when not in use and pads protect the trunk and hatch.
Apologies that I no longer have the instruction manual for this carrier, but Thule provides fit information at http://www.thule.com/fitguide/default.aspx?language=en-us&market=us
