Looking to buy a roof box for my car - got a A4 Avante. I currently have Thule Aero roof bars which i use with my two Thule 591 cycle racks. Looking to buy a roof box too, as when we go away with the dog in the boot, all our gear has to get crammed into the back seat. Im looking for recommendations, and wondering what any of you guys use - ideally i need something that will allow me to fit at least one cycle rack. Oh, and being a car snob, it need to be gloss black to match the cars paintwork.
