I have a Thule short type roof box, a recommended Mazda accessory, And the Mazda CX3 roof. Bars for sale. These have only been used once when I first purchased the car in November, 2015. And are no longer required as I will be changing to a larger car.
These items are currently listed as The CX3 Travel pack in the Mazda accessory brochure at £450 with the safety kit.
They cost me £400, will accept £295.
