Just a note about what people are saying about Thule and Yakima or similar racks damaging the paint..
They are not designed to be left on the vehicle permanently, although they certainly can be left on all the time, as that is what most people do. What is recommended, is that you at least take them off once a year to do a thorough wash and wax of the roof, especially waxing where the feet sit on the paint. As far as rubber door seals starting to leak, proper maintenance can help that too, although I have never had a problem with them leaking. 303 aerospace protectant or something similar should be applied to all rubber seals and and plastics, especially those exposed to the elements.
I have had thule racks on all of my vehicles and I am a certified installer for Thule and Yakima as I have worked part time for Eastern Mountain Sports for almost 5 years now.
