I'm gonna vote Subaru, I don't have one, but on of the LBS guys does. He can get his gear, a full size canoe, mt bike and road bike in/on that thing (it's an amazing sight).

I have a roof rack on my little saturn, and it does add a little wind noise, but if you cut the bars to fit your roof it's barely noticable. Even with my little car I could get a bike and a white water kayak on the roof.
