I have had a 2" hitch mount on my Jeep Grand Cherokee for the last ten years and use a Performance Export 3 bike hitch rack, which works great. I have used trunk mount racks in the past, and would never go back. The commuter car we bought several years ago for my wife, a Ford Taurus, came with a 1 1/4" hitch. It was an easy matter to get an adapter for the 2" hitch rack and it functions well, just like on the Jeep. The only concern is less ground clearance than with the SUV, and that is a function of the hitch on the Taurus rather than the adapter or rack. It does drag going in and out of some steep drives. It does no damage to the rack or adapter.

The ease of mounting, stability, protection and locking security of the hitch mount is wonderful. I have used roof racks for many years with boats and canoes. I cannot imagine they would beat the hitch rack for bikes. And then there was the time my wife tried to drive a van with two canoes on the roof under a carport..... it was not pretty.
