I used the fork mount rack for years... on my latest car, however, I got a deal on craigslist for a used Saris roof rack that kept the wheel on the bike. It has locking 'jaws' so I can lock the bike on the rack, and is stable. I have driven the car with 3 bikes on the rack at 70+ mph on the highway with no problems. I like the fact that I don't have to take the wheel off...but it wasn't the reason I bought the rack. It was a question of price... the Yakima and Thule racks similar to what I had before were around $450 new, or $150-200 on the craigslist in DC. The Saris was $100

I have never owned a rack that mounted to the trailer hitch.
