FWIW, I have a nylon strap-mounted rack (name withheld to avoid accusations of ninja advertising!) which hooks onto the trunk seam. 6 hooks and it's brilliant. Much cheaper than a hitch mounted version, much more compact so I've been able to hang it in a little storage closet in the last few apartments I've lived in and goes on a wide variety of cars without any damage. Rock solid with 3 chunky mtbs on it too. I've even had people come up to me in car parks asking me for details!

Not wanting to derail the discussion but if it was that that put you of the review site you mention, it could be worth reconsidering..
