The boot capacity of a Golf station wagon on the roof

I use the Motion 900 on top of a 5 Series BMW's (F11). The proportions fit here perfectly. It has hardly any wind noise, even 140 km / h are pleasant to drive. The increase in consumption was surprisingly low (approximately 0.6 l / 100km). Apparently you have invested a lot of time in the aerodynamics.
The load volume is gigantic. Our child car and child bike trailer fit folded pure loose. The lock is sophisticated and works very well. For the standard BMW base support system I still needed the optional mounting groove.
The box to be mounted alone proves difficult: it is already very large and heavy. I needed the help of a second person. Also, I recommend lift for the garage ceiling: this is the installation and loading becomes quite easy. Purchase recommendation
