A Cali tailgate is a lot harder to close when the chairs aren't in the rear tailgate storage position. A VW bike rack cant be used in conjunction with a tailgate spoiler either.
Our first van did not have a tow bar so could not fit a sport line spoiler, one reason why we specced one on our current van. We use a tow bar mounted rack which slides and tilts allowing the tailgate to open without removing the bikes, great when the dude at the tunnel/ferry asks if you have gas on board and wants to check its turned off. Also the bikes sit high-up on a VW rack not good for height restricted places like carparks ferries etc.
