More than one bike or just one? I have a station wagon but I only carry one bike in it. I take off the front wheel and put the bike in the back in its side with the DR facing up. It has worked fine for me. If I needed to carry two bikes, I would probably buy a roof rack. Both my wife and I have been rear ended before so hitch racks make me nervous.
When I do get a roof rack it will probably be a Thule Big Mouth since I trust it more than fork mounted racks. My bike doesn't have lawyer tabs so fork mounted racks are probably not a good idea.
