I don't own a receiver hitch rack. I think that the Thule version used to be called Sportworks or something like that. Those have favorably impressed me.

We carry our bikes inside of the cars. I have a bike workshop that occupies the front of my garage so our cars, even without a hitch rack, barely fit. When I bought my Honda Element my prime requirement was for a car that would carry out tandem on the inside yet still fit into my garage. Our Screamer recumbent tandem barely fits inside of the Element but that's good enough. When we bought my wife's recumbent trike, we drove her Saturn to the bike shop and told them to sell us a trike that she could fit inside of the car.
