I'm very pleased with a 2013 2-bike, Thule 9001xt, which I got for a nice price last Spring on a lightning deal at Amazon. It installs easily and securely with two adjustable and lockable steel cables and two hooks attached to both trunk top and bottom. It stays on all season without any adjustment and the design allows neither the rack nor full bikes to budge even at highway speeds. I just use a number of different bands/ties to keep the front wheels from rotating. I wrapped the four hooks with duct tape to minimize damage to the trunk paint. I mostly transport only one bike. After the first season, the trunk was unharmed and the rack is flexible enough to accommodate a variety of frames. The only "flaw" is that you have to keep the carrier arms extended even when you're going bike-less or they will block your license plate. The rack is big and solid enough to inspire confidence it will last for years, and compact enough to go into my trunk in the off-season or any other time. Check Thule's fit guide to see if the model will fit your wheels.
