Have a look at my thread above (specifically, the pics of the Subaru). Now, my dad reckons that the roof bars by themselves, create more wind noise than with the box mounted.Could anyone tell me if some roof racks are worth the investment or if the noise (even with the aerodynamic ones) is too much for long trips? Better get a roof box instead?
I've only ever driven him with the box mounted, and I can say that the noise is totally acceptable - between my music and the fact that the tires are relatively quiet, I don't notice any intrusion into the cabin.
Box is a massive plus. If you can get one, do it!!!
