I have an Infiniti G coupe, and I got the Yakima BigJoe Pro 3 to make sure it cleared the spoiler.
I originally bought the Pro 2, for our 2 bikes. But the bikes load on the rack way too close together, so I returned it and got the Pro 3.
Frankly, I don't see how any supposed 2-bike rack can handle 2 bikes without them clanging against each other.
I bought the tube top adapter for my wife's bike and it makes loading her bike a LOT easier. I also bought the Thule Passive Security Strap to "lock" the rack to my car.
