I did a lot of research before buying this rack. I'm happy with my purchase. I didn't give it five stars because, while I think this is a great rack, I'm not sure any trunk rack is a five-star bike carrier. My research told me this one is probably the best trunk rack, and after receiving it, I believe that is true. I am using the rack on a 2014 Audi A4. The site said Bones 3 would fit, and it does fit very snugly. When I filtered available Saris racks by ones that would hold my carbon fiber bike (Trek carbon road bike), this one disappeared from the options list. My bike store contacted Saris, and they said it would be fine. However, not all carbon frames will be as snug as they'd like. I have been very happy with how well my bike fits. At highway speeds and over bumps, the rack and the bike both look very secure with very little (if any) sway. I also purchased the cross bar (accessory) to carry my wife's bike (Trek hybrid woman's bike). Her bike sways much more than mine does, but not enough for it to be intolerable. The cross bar doesn't seem capable of giving that tight, secure, no-sway fit that the bike frame itself gives, but it gets the job done, and I'm happy I can carry both bikes. The first time I setup the Bones 3 it took a while to configure. Now, I can easily set it up in five minutes. The bottom line is that if you're in the market for a trunk rack, and you're considering Bones 3, then I do recommend this rack.
