Having done lots of research, I mistakingly bought the VW rack. Whilst the quality is good, the VW rack has a number of pitfalls. I found the height to be a pain after a while, in addition you can't open the boot with 3 or 4 bikes on and finally, you can't get spares for the main components, should any become damaged.
This is what happened to me, and because I couldn't find a replacement, I bought an Atera and I have to say that having owned both, the Atera is certainly the better rack. To my mind just as good quality.
Whatever you choose, you should bear in mind that there are many other quality racks on the market. Good luck and I hope you find the right rack for you.
