The Mazda CX 9 is an amazing SUV- very spacious, powerful, and sleek. However, with the introduction of the 3rd-row seats, the trunk space is reduced drastically.
For example, the car has a cargo space of 38.2 cubic feet behind the second-row seats. This figure drops to 14.4 cu ft. when the 3rd-row seats are lifted.
While it’s not for cars in its cars, it surely won’t fit all your gear or cargo on your next road trip.
That’s why you need a roof box to supplement that space. Below you’ll find details of some of our favorite Roof Boxes that will all fit perfectly on your CX 9.
