Roof Box (Audi Store) manufacturer

[derekjspence]

Can anyone advise on the manufacturer of the roof boxes available from the Audi Store? Example of one in this link
Audi Ski and Luggage Roof Box - 300 Litres (https://store.audi.co.uk/audi-ski-and-luggage-roof-box-300-litres-8v0071200y9b.html)
I am looking at getting a hold of one but the prices are pretty damn high and my local dealer says the very same make are available on the market outside Audi. I forgot to ask what brand they are.
Another question on this. My A4 Avant is Daytona Grey and has the extended black styling package. Should I buy a black or grey/silver box? Im thinking black.

Thanks for the responses

I have a B8 Avant in Lava and have a black Thule box and love the combo - so black for me but I am biased and have black box!

It is by Thule and still expensive, if that jolts get down to Halfords....
