This is Citroen's own bike rack specifically for an early model Citroen Berlingo, fitted in the photos to our 2007 model. Since it's a custom rack, it's effortless to attach, with two hooks hanging off the top of the rear door and two rubber feet resting on the sides. It has two rails to fit two bikes, with straps that attach the wheels to the rails.
However, since it's tailored for this one vehicle, I'm pretty sure it won't fit any other car. I think even the newer model Berlingo has a different, more sloping rear door so maybe it doesn't even work on that. If you're interested but have doubts and live near Oldfield Park, just swing past and see whether it fits to your car.
