Thule Vertex 4 bike rack with a 2” trailer hitch receiver. over 10 years old. My minivan used to drive around with 4 bikes on this rack--my bike, my wife's bike, and the bikes of my 7 and 4 year old boys. Haven't used it in 9 years. It's in good condition--the arm opens easily, but the other swivel piece will need some oil or de-rusting so you can open your trunk.
I got a new bike rack so I no longer need to keep this one, and I'd like to clear out some garage space by giving this away.
