Roof Box for Q3

[fly fisher]

With the arrival of twin boys and the household cars being a Morgan and a Q3, we will need a roof box.

What is the biggest roof box you can fit on a Q3? No need to take bikes etc so happy to go full width.

Many thanks
Will

Probably beneficial to pop into a local bigger Halfords and take a look at them, no need to buy from them but it will give you an idea of sizes etc.
They should be able to advise on what will fit.
